W220 sometimes goes out and after time back on and later…

Hello Have the following problem. First it was the following… You could drive normally when you parked it and e.g. went shopping he didn’t jump on after that* After a few minutes everything was ok Today I was in a workshop and they changed the petrol filter (at my request). I got out of the workshop and drove a little afterwards braked because of traffic lights and the engine went out. But it doesn’t always go out as soon as I stand or the revolutions go on stand gas. Got it again After about 10 minutes he went on and I drove back to the workshop (no Benz workshop). According to the mechanic, you could not find a fault by connecting the diagnostic device. The petrol pump probably does not get any juice because he checked it. Which relay is responsible for the gasoline pump they could not check because you did not have the information in the program and it was just before worktime. Returned home and after some stop&go again from u And after about 15 minutes it went again. In front of the garage stopped and you can imagine what was *When turning around the key everything is normal to the last one, i.e. it sounds like there is no fuel. So I write it this way… Keys turn around dududududududududududududududududududududududududududud, etc. until I turn around again to turn out, so to speak. Can someone please help?
