Default Random power drop in my 2012 Etios GD

I am in possession of 2012 model Etios GD. It has clocked 62000 kms. The car is in mint condition other than the clutch pedal which are little hard to press. But it never slips. I use this car only for highway driving and rest of the time it is parked in an enclosed garage. In last three months I encountered strange problem of random power drop. Firstly I ignored thinking of my wrong illusion of problem which doesn't exist. Recently I drove it to Raurkela and returned Ranchi in same day covering 495 kms. The road condition is so- so (Two Lane, Hilly terrain with some pot holes). While going to Raurkela car was in fifth gear and I removed foot from accelerator pedal to get speed reduced for crossing the rough patch of road. This was done for few seconds only and I again pushed the pedal in same gear. But the engine didn't responded and I felt loss of power. It may be mentioned the speed of car was plus 80 kmph and there was no need of bringing it in lower gear. For half an hour it continued and I encountered the problem frequently. Switching to low gear gave the remedy otherwise the car jerked. After half an Hour the problem vanished. It ran smoothly for next one hour till I reached Raurkela and parked the car. In return journey the same happened for half an hour and the problem vanished. It gave me tension as what I have heard Toyota for their mechanical reliability and sturdiness. But this incident shakes my confidence. I am in habit of long solo drive and if the problem is not diagnosed and rectified then it might be a problematic affair for me. My other cars are 2006 model Maruti Zen Lxi with 25000 kms of odometer reading and 2003 Mahindra 540 DP with 85000 kms. Both are in stock condition with no engine or clutch overhauling. I am very particular of timely servicing and that too in self presence. I use to clean air filter after every long driver with a handy blower with high pressure. For the Etios I would like to underline the followings.
• I am the second owner of the car. Previous owner was a doctor who used it only in city limit of Jamshedpur and generally it was chauffer driven.
• Car was purchased with odometer reading 0f 52000 kms and service record showed oil was changed on 49000 kms. So I got the oil changed on 59000 kms with oil filter and Cabin AC filter.
• Here I must admit that these works were carried in neighborhood garage as I thought changing oil is not a very skilled job.
• I used Servo Premium CF -4 (15 W -40) oil, purchased from a reputed petrol pump. The Oil filter I got online whose brand name I don’t recall.
• I use to purchase Diesel from a reputed fuel pumps. This time I had full the tank from a dealer opposite DPS School on Ranchi by pass. BHPians from Ranchi may endorse pump reputation. Generally every time there are lots of customers. The Pump has facility of free Nitrogen, air and of course free music in air. But seven years back the pump was sealed for six months for selling contaminated fuel.
• Whenever the problem occurred the AC was on and it was hot outside. (Plus 35 Degree Centigrade ).
• Only one person was sitting with me with no weight in car.
• As Etios dashboard gives no numerical display of engine RPM, Temperature, Oil Pressure it is difficult to comment on these figure during and post problem.
• I peeped into engine bay and found every pipeline intact with no sign of leakage of any fluid, gas etc.
• Google suggested me for dirty MAF sensor which I found super clean.
• Google also indicated fault in catalyst converter. It suggested hammering it from outside and if there is some rattle sound then it has to be changed. But I am unable to check it.
I am hopeful for getting solution/suggestion from fellow BHpian. Toyota dealer in Ranchi service reputation is not up to the mark. Today in Facebook one of fellow 4x4 member has shown his disappointment with the dealer for not giving solution for brand new Toyota Crysta.

Is the car engine temperature fine or the engine cooling fan working fine? I hope the engine is not getting over heated. Though in that case a warning light will come up in the dashboard. If the engine is not getting over heated, get your AC compressor checked by a good AC mechanic. If the AC components are working fine then the next steps can be the following-

Connect a OBD scanner and check out for the error codes.
If it shows no error, you can check the following-
Throttle body cleaning
Change the diesel filter
Condition of the glow plugs
If there is any clogging in the fuel line
Reset the ECU once
Clean the EGR valves
Check out for any leak in the turbo hose
Check whether the turbo is in the verge of a failure or not. As you are the second owner, you never know how the first owner treated the car.For example whether he used the idling practice or not.
And lastly check the clutch plate

Samba your suggestions seems near to the solution. Major of the suggestions require involvement of mechanic/service center which I should adhere to. I was knowing that only Petrol engine with Multi Point Fuel Injection has throttle body. Please correct me if I am wrong. Secondly glow plugs only function in heating the combustion of air and fuel during firing of engine. Rest of time they are idle.Waiting for your valuable comments.

You are correct, i am wrong. I just goofed up with a petrol. Many diesels have throttle valve which are generally referred as air management valve. In modern diesel engines, its electronically controlled.

True. I mentioned the glow plugs primarily as a check up. In case of a faulty glow plug the vehicle should miss fire, that can lead to a loss of power. In most modern diesel engines if the ecu sense a failure it can lead to loss of power or even take the car to limp mode. So still i would insist if the other aspects are found to be okay, do have a check at the glow plugs once.
For example in the new generation Ford Figo/Aspire even if the air filter is chocked the car goes to limp mode and do not rev beyond 2,500 rpm with the check engine light on.

I was driving on highway and after 70 Kms I noticed dip in power and it was difficult to overtake and on fly-overs the car was just not moving without shifting gear. Still it was able to do 90 - 100 kmph on straight roads.
Checked the EGR, it was clogged with soot. Blocked it and the car was ok for one week, and when I went for a long drive with 5 people on board, the check engine lit again. Meanwhile a person called after seeing the ad in OLX. He came to inspect the vehicle and was pretty ok with it. I informed him about the complaint and he was ready to buy the Quanto after checking the service history. Went to a trustworthy and equipped workshop with the prospective buyer, they checked the air filter and MAF sensor. The filter was clean and sensor had oil particles on it, cleaned and put it back. The mechanic said the Turbo is fine and there is no issues with the vehicle. The buyer was ready to take risk and I offered the vehicle at a much lower price considering the issue. The Quanto affair came to an end on 19th September 2016. Now I am left with no vehicle hoping the Vitara Brezza ZDI booked on 5th September will reach me by November end.
