1992 3.1 stalling

my rodeo is keeps stalling on me. it runs smooth and normal and then it just shuts down. it is not gettin fuel to the jets. i replaced the fuel filter and put in gas antifreeze, and also used a heater in the garage. itll start and after a while running itll just quit, when it sits for a few hours itll start again. help someone?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?

maybe your fuel pump is on the way out? Or maybe the Fuel pump relay?

Check the fuel rail and see how much pressure there is and also replace the fuel relay (relay is the cheap fix).
