Cuts Off

2004 F250 6.0L purchased 2 months ago. 145k miles.

At high speeds, truck starts to "choke" or "starve" for fuel. When you slow down, the engine just cuts off. This happened a few months ago and I replaced the fuel filters with no problems since.
4,000 miles later it is doing it again. I wouldn't think the filters would be bad again? I do know it needs an injector on the 7th cylinder but do y'all think I need a fuel pump too?

04 has no STC. Id be more inclined to see what your fuel pressure is with KOEO. I had a truck that would run on 8psi of fuel pressure. Dunno how. It would occasionally shutdown. Good Luck

Cuts Off

If it's a late 04, check the throttle body butterfly for proper operation or coked with soot.
