is there an emergency fuel shutoff
Nope, that's a Ford thing, at the age of the vehicle it's time for the fuel pump to give up, some will make a whining sound just before they quit, others will just quit with no warning, so check for power at the pump when you first turn on the key, and then the ground, if you have those and the pump and still no fuel pressure then it's the pump itself. Don't forget to replace the fuel filter and relay when you do the pump so the warranty is covered if something does happen to the new unit.
