F.O.R.D.=Fix Or Repair Daily

Immobilizer could be shutting down the fuel injection.

Check trouble codes with a scanner. It is likely time for timing chain and cam phasers change if you have a 5.4. $2k fix. Or it could be a bad (hard wired) fuel pump relay that requires changing the whole fuse box on the passenger side kick panel. Or just a bad crank sensor.

Too many possibilities to guess, but you might get a clue pulling OBD2 trouble codes.
