Yesterday when I drove my Linea after not using it for three days, I experienced temporary power loss for a few kilometres. The engine was taking for ever to rev from 2000 to 3000 rpm and when coasting there was also something that felt like sputtering. I pulled over, switched off the car, and restarted it after a few seconds - and it was all back to normal. Drove as smooth as always!
I had experienced exactly the same thing 4 months back, when the car hadn't been used for a few days. This was about a week after the second service.
My car has done 16k km till date.
Is this a normal thing?
Or is some part failing?

Did you notice exhaust colour when this happened?

Check your fuel filter. Sputtering is a symptom of a bad filter.

You should probably ask the dealer to check the EGR Valve.!.!

Okay, so I'll take the car to Service and have these checked. But the problem is, I have exams at college till Thursday next. Can I delay this till then?

And by the way, I used the car today, and power seemed normal. The turbo whistle sounded as usual. But when I floored the pedal a few times, there seemed to be a faint hiss past 3000 rpm. (But I could have been imagining this).

I am with catalyst's opinion too. Fuel or air. One of these, or both are getting starved, when you demand for more. One more thing which can't be ruled out is presence of water in fuel. But I think, there must be an indication for this in your car. Well, service centre is the best place for solution. Here we can discuss the possibilities. Get it done when you are free. And let us know your findings.

I have faced this issue twice in my linea and both times it cropped up after driving continously for 150kms or so.
It feels like you have lost all the power,and flooring the pedal has almost zero affect in Acceleration,in my case i didnt turn off the car,down shifted to 4th,and there was this turbo spool acceleration at 3K+ RPM,and it behaved normally after that.Since it would be really difficult to replicate this issue,the aftersales guys hooked up the scanner to find no error codes.

Recently timing chain for my car was upgraded to that of 2012 models,and i have driven for 200kms at a stretch twice after that,dont know if its related or not,but after the chain was replaced,i havent faced this powerloss issue.

^ Yeah, it was almost like the accelerator had been disconnected. The problem arose after I had driven about a kilometre from home, and downshifted when nearing a junction. Lasted till till I switched off and restarted the engine.
I don't think it's easily reproducible, and I doubt if TASS guys have the acumen to make a diagnosis from history alone. Also they're woefully overworked, so wouldn't want to spend much time on this issue. But they have put their best man in charge of Fiat, though.

Interestingly, I too faced the same problem 2 weeks back. I thought it might be bad fuel or something in those lines. Though, I faced it only once and no such problems after that.

Have you driven the vehicle with very less fuel in the fuel tank?

Never. We almost always refill before the low-fuel light comes up. And always top up the tank.

When you visit the bunk next time, ask the attendant to fill the tank in slow setting (the nozzle has 3 settings) and check if you face the issue again.

Filling up in the slow setting? How will this help?

I had faced similar problem with my Indica. My regular mechanic said that sometimes when you fill petrol in the fast setting, there is a chance of air getting trapped in fuel lines and the remedy is to fill petrol in slow setting.

I have been doing this for many months now and haven't faced the issue of sudden loss of power. Hence the suggestion.

I have faced this problem,and i know,it has nothing to do with the amount\quality or how you fill diesel.
