There are two "usual suspects" for this.
a) The OVP (Over Voltage Protection) relay, which is what you are referring to. b) The switch portion of the ignition switch assembly. If you wiggle the key in the lock, you might be able to start the car. If it does, the swtch is the problem. There are descriptions of the procedure for changing it out on the forum. Good Luck. Scott

Add a 3rd suspect, the fuel pump relay located behind the glove box on 560s.

I'm with Dugald on this one, with the ignition switch a close second.
Sadly, actually diagnosing an intermittent like this is a pain. Often you end up just being a parts changer. ![]() |

I would not suspect OVP in this case.

I Agree that it doesn't sound like the OVP relay - an OVP relay fail will normally only drop down the power rather than cut off the engine completely as I've had happen myself recently

relays
I would have to go with the fuel pump relay, had the same problem with an 89 300TE, replaced the fuel pump relay and problem was gone
