Motor would cut off! No electrical interruptions, stopped while shifting, idling, running down the highway (at 60 mph), doesn't seem to matter. It's infrequent, no regular pattern that I can see. I've replaced everything electrical as well as the fuel pump, muffler, timing chain. It's getting to the point where I'm replacing parts that still have their warranty (I'm on the third computer), any help would be very much appreciated.

I've used synthetic oil every 5000 miles since 50,000. The motor still runs smooth except at idle where there is a slight surging of the speed.
