Truck runs like a champ on cold days, but when it warms up truck runs bad after it is restarted after 15 to 20 minutes it is like it is starving for fuel. Fuel pump is new 3 new fuel filters new pressure sending unit ,it bucks jumps spits and sputters, only runs bad for a few minutes then runs ok, only runs bad after it is restarted

 

if your engine is TBI then check your choke, it might be getting stuck
