From what I read, the truck will run so long as you spray starting fluid in it, but die on its own. Try checking the fuel pressure at the regulator. Even after replacing fuel pump it might still be low.

If you replaced it, assume it is good. But check things like fuel pressure regulator and fuel filter. You also need to know what type of fuel pump your model needs: Z or W. One produce lower fuel pressure (less than 15psi) versus the other, which produces 55psi. May want to pick up a manual for this. It will instruct on how/where to test fuel pressure. Also if fuel pressure drops quickly after switching off, it will indicate a mechanical problem with fuel delivery system.
