Has anybody had the problem of a g60 cutting out for no apperent reason? It will be driving fine, then the tach drops straight to zero and the car dies. If you let her sit for about 5 or 10 minutes she starts right up. I have a new ignition switch, and no vaccum leaks. Also new lambda probe. I can hear the fuel pump, so i think its the ignition. Today when it happened i unplugged the power wire to the coil and re-attached it and it started up, but it could be coincidence. Please help
