i am pretty new when it comes to the gasser engine on these,mainly run nitro.
had you tried resetting the needles back to factory settings? i do recomend you to take note of where they are at now as well.
checked the idle gap as well?
dies even with slight throttle blips or when idling?
checked the plug?
may be a fuel system leak? i think these are pressurized just like the nitro models and air leaks play havoc on tuning and if bad enough, on running.

Have you tried a new glow plug?

We need to know what engine is in the truck, what fuel you’re using, what glow plug or spark plug, and what you’ve already tried. Based on the OP, it could be any number of things causing trouble.

Dump the .31 gas engine. They’re nothing but problems. Honestly - nobody has had luck with them.
