Make sure your tank is venting. A plugged vent will give you that exact problem. That is, runs fine for a while and then just acts like it's not getting gas, bucks, won't go...Let it sit a while and it will run fine for a while...
******
Venting has never been a problem. The PO has this crapola locking cap that does not lock, it just rattles and can be taken off with no problem.
The early problem was sort of opposite of what you are saying.
I'd get gas, then take off. I'd have a speed cap, usually about 60 or less and I'd have to pull over for about 30 minutes. When I got back on the road, it ran find until I filled up again.
Obviously, the scenario has changed, probably with the changing of different components as we found bad ones.
NOW, when I had the external gas tank connected to the engine mechanical fuel pump, I could run down the road 75 with no problem.
BUT connected to the GMC gas tanks, its different...
When on the main tank, with no electric pump assist, the float bowl will go empty and the engine stalls.
How do I know the bowl is empty? when I turn on the electric fuel pump to purge the gas line and carb, I can hear the gurgling of the gas filling the bowl.
When on the RESERVE tank, which uses the electric fuel pump, I can get up to 55 mph before the power problems begin...
Everything is new, hose, from the front to the back to, and including, the fuel solenoid valve.
I'm sure someone might recognise these symptoms, but they are different depending on the source tank.
I'm just glad I can drive her again, FINALLY!
