Temporarl Lost of Power in ML320 Need Help

[kupiec79]

Just bought my ML320 2 weeks ago and already i have a problem. ( Car is not under warranty anymore )
First it happend maybe once every 1-2 h, right now ist almost every time when driving.
Here is the problem.
When i stop at the light or slowing down to about 5mp/h engine statrs shaking and feels like is about to turn off.
Then when i am pressing acceleration pedal car is not responding for about 2-4 sec. When i press it all the way
its taking off but very slowly. After that runs perfect.
Feels like there is no power. There is no check engine light on.
Thanks for your help.
