I may have missed these, does the truck die just sitting
& running? & did you inspected the inside of the tank
for 'floaters' that would block the pickup tube?
Thx.
I haven't just let it sit for a long time idling waiting for it to die. But I pulled over before a mile of driving when I know it's close to running the carb empty and watch it finish running out of gas and die.
Tank looks clean and it happens like clock work. If it was something getting stuck to the pick up tube it wouldn't happen the same time every time
