Try unplugging the front O2 sensor and see if it stays running. Could be bad and once the engine tries to switch to closed loop, it's getting bad info from the O2 sensor.

Yes I watched at the fuel rail fitting. When the engine quits FP drops off. Reset the key to start, FP rises again. I cant say if pressure drops before the engine quits.
All Im looking for now is the AutoShutDown relay on a 92 4.0
DOes anyone have a clue?!

Note from DJ
I guess you forgot that in your other post you were told where to look for the ASD relay!
92 4.0 Dies when warm.
