ED9man: Thanks for reply.
You're talking the ground from valve cover to body? I did notice it was a little loose yesterday at the valve cover. I'll tighten it and see what happens. This is a very erratic intermittent problem. Yesterday was at lower rpm and died; would not start for 5 min. or so, but when it did was fine.
Also, checked the code after it died this last time. Was Code 1--ECU failure. If that is true then it is again a very erratic failure. If it is the ECU, why would it fail so erratically? Curious. Thanks.
