hi ... lol! is that how you emphasizethings ?? runthemalltogether if the fuel pump doesn't run when turning on the key, I would work on that for sure. likely suspect is the ECU. fuel pump relay possible but unlikley. for just shutting off, I would sure consider the distributor/hall sensor. fwiw, I have not seen that failure 'in flight' ..except for cutting out/jerking .. and not a clean shut off ... though it does match the symptom of a clean shut off. I figure we can expect that communication will just get sloppier and less clear as time goes on- apparently.
