I bought a 95 SL500 a year ago, when I bought it I had no engine problems, but had to replace the wire harness and instrument cluster. Since then the car will run for 10 min then the engine stops, crank crank seems like there is no fuel then after 45 min the engine starts with a stutter and then runs smooth and doesn't die anymore.Mercedes changed all the filters, drained the fuel tank then had me change the ignition coils and fuel pumps. Car always runs fine when I drive it home from the dealer but the next time I drive it it stops after 10 min again. I live in the Philippines and there is only one authorized dealer. Beautiful car but its just sitting in the garage. Any suggestions on what it could be thanks

 

Did you try looking at the two distributors and rotors for same? Also, the fuel regulator, which keeps pressure in the fuel lines.

May I also suggest going to your library and check out Alldate.com. I don't know if it's the same for you, but here on Long Island,NY, you can access it for free.

Before you changed the harness, did you have this problem?

Look for simple solutions first.
