truck dying then wont start

this is my fathers truck, i will relay the info as best i can.

started the truck up this morning and while it was warming up in the drive way it just died with no warning. just as if you had turned the key off. tried to start it again, would only turn over and not fire. shortly after the theft light came on and stayed on. still truck would not start. once the theft light finally went off the truck started again. but once again it ran for a bit then just died with out warning. it keeps repeating like this and we can't find a rhyme or reason to it.

oh and it's a 2000 7.3 excursion 4x4.

Sounds like a PATS issue

I'd say the alarm is messing with the PATS system

Take it back to Ford and have them check the PATS system. If it checks out, the disconnect alarm box.

it wont make it to the dealership, and towing it an hour and a half is not an option.

Have fun then. You can try disconnecting the box they installed but without a wiring diagram and it's not gonna be easy.

You could go the cheap route and try the camshaft position sensor... Keep one in the glovebox anyways.
