stuck

my 88 f250 5.8 5spd seems to have the worst fuel milage ever, what has me stuck is i can pull the plug wire off any cylinder and see very little to no change same with pulling the injector plug, but it runs great (other than mpg) plenty of power. occasionaly it seems to load up on me and it dies if it sits for a little while it starts up sometime having to do this multiple timesbut not back to back when it starts it will run a little while approx 5 mins then dead again if i try to start it right away the starter seems like it has no power but after it cools for a min it starts right up this problem occurs about twice a month now the rest of the time its just running rich

Get your injectors cleaned/replaced.

I don't know if the injectors are the same, but I wouldn't seafoam for this.
