I have a fleet of FMTV's A0's A1's & A1R's - All run great except 1. It's been flashed to 330hp and has 307 gears, like the other A1's in the fleet. This truck, runs great for about 4 miles, then slowly loses power. Pull over, shut it down, let it sit for a minute or two. It fires right up and takes off like it should. A mile or two down the road, same thing. Over and over again.
No check engine light or strange sounds, just no power.
I've changed the filters and flushed the tank. Primer bulb pumped right up. (This gave a slight improvement, but still behaving the same way. However, It will recover when idling at a light now and take off as it should, only to lose power once again).
Fuel lines all look good. Tried running it without the gas cap, Thinking maybe it's sucking air in the fuel feed? Checked all the connections. All look good and are tight.
