im trying to think this through a bit.. as far as logical scenarios that could replicate the symptom..

im guessing, that since there are 2 check valves on the tank, and a ball in the filler neck, that the chances of them all three causing a closed system vacuum , that might keep the fuel pump from pushing out fuel, that seems like more of a statistical oddity.

i do agree with the evap canister recieving gas, but wouldnt you see signs of that from the purge solenoid malfunctioning and throwing a check engine light?
especially since the evap canister is positioned well below the top of the gask tank?

I had the thought of replacing the evap canister, just for grins, but my deal is, how much money do i throw at this problem, without knowing the full extent of the problem?

It seems to me that the frequency of occurence, with other owners/vehicles, is quite a bit..

This issue has been discussed numerous times...
Guys fill up, and their truck dies when going around a turn.

Check valve is the problem with shutting off apparently.

Usually I see this being the issue when someone allows the truck to run out of gas. I think it loses prime. I know for a fact if you install a new fuel pump and don't prime it you experience the same issue. I've been told by more than one Mopar tech that runing out of fuel to the point of a stall does irreparable damage to the fuel pump and it will periodically stall until the pump is replaced.

Yeah, running fuel too low burns up the pump. Fuel is the cooling agent for a fuel pump.
I tell my wife all the time to stop running the fuel so low. been telling her for 9yrs. She keeps saying. I know. I know but nothing ever changes.

Generally fuel pumps die when you park a perfectly running vehicle, let it cool for maybe 10min or so and then try to start it again. Sometimes it happens at the pump..lol
