You need to check the oil pressure fuel pump switch unit as it is what keeps the fuel pump relay energized. No oil pressure signal then relay drops out when you release key switch from starting position.
The reason it will start is the computer turns on fuel pump for 5 to 7 seconds for starting.

Happy hunting,

if you hold the gas pedal slightly down and it stays running, then its the idle air control motor stuck closed. its silver and sits on top of the intake. a tap of a hammer will confirm. fords do not use the oil pressure switch for the fuel pump. they use the crank/cam signal.

OP says '97 Ford. What year did they go to crank/cam sensor?
If it uses a crank/cam sensor then it should be checked.
