Pugram, Xetas are sensitive to adulterated fuel, yes. However your problem had to do with overheating. When the car heats up too much it looses power and behaves like a ton of bricks. It feels like it would rather shut down than move. Even on 1st gear when you try to get moving it shudders and tries to shut down. This happens when the outside temperature is too high and the cars cooling mechanism is not able to cool the engine down even after putting in all its efforts. This problem is also experienced when you are stuck in a jam and continuously driving on the clutch in 1st gear with the AC on. A bad summer is only aggravating this problem a few folds more. I think in these scenarios the best solution is to stop somewhere and take a break. Better still lift the hood and let its cool down somewhat.
