My truck has me baffled

My old 4.9 did that for 2 weeks on and off then the fuel pump went out .. replaced both the front and back pump ( had duel tanks) then it worked fine but would always overflow fuel if you filled both tanks up... It would leak out the front for a few minutes are so..Also check the tightness of your spark plugs .. one of mine would work itself a little loose..
 
Needed clutch kit ... that was fun:secret:
 
Just put another coil pack on my truck,,,3rd one in 2 yrs....guess not too badk for 113k miles and all the pulling I do. But at $170 plus for a coil pack and plug I will be doing the next one myself!!!
