truck runs for 5 to 15 minutes then shuts off but will restart within 1 or 2

no its not that's whats so strange

I replace my fuel pump about every 16 to 18 months also fuel filter I think it must be something wrong with electrical in truck but replaced fuel filter when problem first started and truck ran great for about 3 weeks

Sounds like mine also. I just replaced the fuel pump and it seems to be running ok. but i still have an engine skip ever now and then.
