sl 380 mercrdes 1983
 

I have a amazing v8 Mercedes sl 380 and it keeps cutting
Off on me while driving and then when it cuts off on me I pull
Over and let it sit for a second and start it like 3 to 4 times and it starts right up

I replaced fuel pump and fuel filter also ignition coil maybe its the
fuel pressure accumulator !? It can run for hours a day and not cut off
To few mintues and cut off

Sounds like a bad fuel pump relay to me.
