My mercedes c320 2002 try to turn off when driving long distances. The car start to shake and I press the gas and cant run anymore. I wait some minutes and I start the car again and run normal a short distance until start the problem again. If I wait the car to cool down for example I wait like 5 hours the car can run long distances again until starts the problem. I change the crankshaft sensor like a year ago, I change too the battery and the alternator. I don't have any light turn on in the panel. Any one can help me about this trouble?

Have you had the fuel pressure checked?
A faulty fuel pump which builds-up internal resistance in its electrical circuits as it heats up can cause this, so the pressure needs to be taken when the engine is cool as well as when it heats up and the problems starts to occur. (This can be done by driving the vehicle with pressure gauge connected, that way you'll only have to raise the hood to see what the pressure is when the problem occurs.

Have you had the fuel filter changed?
A dirty filter can cause this and is a relatively cheap fix.

No I didn't check the fuel pressure yet. I change the fuel filter already. But I didnt check the fuel pump. The problem never occur in short distances is allways in long distances that start to shake and try to turn off, I press the gas pedal and cant star to run shaking until its stay in the same site shaking.

Today the problem occur again when I was near to my house. I park the car and turn off. I start the car and when the car start I open the hood and the motor it was shaking like trying to turn off. I turn off and in the motor it was a sound like a buzzing. The thing that is rare to me is that allways the car start but sometimes with difficulty when I press the starter. When the car is cold no problem occur.
