Default Intermittent Problem?

94 Ram2500 Stock
After a half hour drive or so park an dlet sit 10-15min then when I start up again it stalls and is hard to restart and has no power like it is running out of fuel. Shut it off for a few minutes and try again and runs great. Any Ideas

THanks in advance

Check your idle, if your rubber fuel lines are stock they could be sucking air, fuel filter, dirty pre-filter at fuel heater.....

Timing.......maybe

Maybe an overflow valve.

Fuel lines look good I will try a new overflow valve and see if that fixes it.

Thanks B

My 97 would start run for about 10 seconds then die it would take about 30 seconds of cranking to get it going again. It was the overflow valve but I also found out that some of my fuel lines had very tiny holes letting a little bit of air in. I guess what im saying is they may look good but that’s not always the case.

before you spend 60+ bucks on the overflow valve, just take it off stretch the spring out 1/2" and put it back in there. See if that takes care of your problem
