crown vic intermittent shut down

did it with the new pedal. Quit twice.
installed the new fuel rail pressure sensor, so far, nothing...but unfortunately, that means nothing. Probably going to change out the fuel pump as that has been pointed out as the possible culprit as well.

should would be nice if it was going to quit on me, it did it more frequently. data logging something that sometimes shows up months later is not a great way to try and diagnose it.

How about a 12volt line monitor? Get one and tap it onto 12v components that might have a wire break issue. The monitor should record how many times power was interrupted.

wasn't aware of something like that. how does it know the history?

and for grins, upon a suggestion from a well trained mechanic, went ahead and replaced the fuel pump assembly and it died on me the next day. this is really getting old now. I am wondering about the ignition switch.
