Saga Continues - Stall 560 SEL

[waylifeshouldbe]

I've reported this anamoly in the past. My 1988 560 SEL is still stalling intermittantly. This morning, traveling at 60 MPH, 27 degrees out, tach goes to zero, car is off as if I turned the key to "off", I pull over to slow lane, coasting now at about 40 MPH, car comes back "alive" and drives fine. Total time was about 15 seconds. I have replaced cap, wires, coil, rotor, and fuel pump relay. If the pattern continues, I'll not likely see this again for another 2-3 weeks. Very bizarre. Any one out there have suggestions as to where I should look next? Thanks for your input.
