MY 92 with a 7.3 everynow and then will fire up run for about a min then die and not start again for like 3 hours. i know i need to replace the gp's i got a new fuel filter on it best i can tell there aint nothin wrong with the fuel system

 

It may be that only some of your pistons are firing properly. Have your piston compression checked. I have bad GP's and mine never does that.
