A couple of problems I was hoping for help on.

I just got an 88 560SL about a week ago. I'm incredibly happy with it and I have wanted one of these since I can remember. I had a huge amount of work done on it, everything replaced as far as wires tubes and such go. The mechanic that did it knows his stuff too and has done a great job working on my dads 86 560SL since before I was born.
He was however stumped by a problem I have been having. It's two fold and I'm guessing they are related. The car is refusing to start back up again after it's been turned off for anything less than 5-10 minutes. I can try, it will refuse to work, and then a couple minutes later it will start up with no problem at all.
Also the car has died a total of three times on me and wont start up again for a few minutes. All three times have been when I was just moving at idle speed or under 5mph.
Has anyone else had these or similar problems? Is it just something I will have to deal with? I've been looking for some answers and found this forum where everyone seemed to be very knowledgeable and I was hoping I could get some answers. Thanks!

I must have said this a dozen times, but hear we go again.

In a no-start situation, the most basic thing to find out is if the fuel pump is running while you are cranking the starter. So someone needs to turn the key, and a helper needs to put their hand on the fuel pump to see if it runs.

Chances are good that the pump is not running and the fuel pump relay is the problem.

Your mechanic should know this.

Yeah thats what I had seen from answers before and checked. That leads to the mystery behind this problem for me.
Thank you though!

So the pump runs while cranking?
