1988 Mercedes 560SL engine suddenly dies/stalls Sign In

I have a 1988 Mercedes 560SL with automatic transmission that is in good condition. It runs pretty good but recently, it has started to have a problem. I will be driving along with everything running fine when all of the sudden the engine just dies. It then will not start until it sits idle with the ignition off for about 30 seconds. This can happen at both high speed and while going slow. I can not determine if it is a fuel problem, an electrical problem, a sensor problem or the engine computer. Any advise or thoughts would be greatly appreciated in helping to diagnose the problem.

Thanks in advance ...

Hokiefan; At the time the engine fails, you'll need to determine if you are losing fuel pressure or ignition spark to the plugs (unless it's a dieselWink). My gut instict, sounds like classic symptoms of an ignition control module failure, but I don't work on MBs.

They are pretty notorious for bad Crank sensors acting like that too.
