Loss of Power in the middle of Driving after Car gets driven for an hour or more

[nido539]

Hi Folks,

I have got 2007 Toy Yaris 1.3L...Fot past few months, it is doing a weird thing...It starts well, runs well for a while and then in the middle of driving, it loses the Power and no matter how hard I press the Acceralator, The Car just drives at 5km/hour speed...Then If I wait for 10 minutes and restart the Car then it runs fine for some time until it repeats the same thing after a while.

Changed the Fuel Filter, Ignition Coils, Spark Plugs and MAF Sensor...But still the Car does the same loss of Power...

Did someone else had similar issue with Yaris in the past...If so, What do u think could be the culprit...?

Could it be a Bad Throttle Body which gets Stuck closed at the time of happening or Could it be the ECU as well...?

Thoughts ?
