    Lots of possibilities come up with stalling problems, from clogged fuel filter, faulty pressure regulator, vacuum leaks, IAC valve, bad injector, even a faulty ECM. Testing fuel pressure at the fuel rail with a fuel pressure gauge might be a good start.

    Having the same issues, fuel pump gauge fluctuating, transmission fuel stick broke, truck shaking, stabiltrak code up etc... Replaced fuel pump, fuel sender, and the volm manifold w/sensor which fixed most of the issues but now im having issues with the torque converter.
