86 560SEL engine quits

I have started experiencing a rather disturbing problem. When I am cruising on the freeway the engine will suddenly quit. I pull over put it in park and it will start right up.

Any ideas?

A bad fuel pump? or the relay? Check the fuel pump relay to see if it is in working order.
