My 1968 250sl, which I just got, has a problem which I have seen several times on this forum. After about 15-20 minutes, it sputters and dies. Wait for it to cool down and it will start, but run only for a few minutes and die again as if it is running out of gas.
I need a good mechanic who knows these cars and the issue,so I don't have to replace everything except the tires to find the problem.
Any ideas and I would be very appreciative.
