Glad to hear the brake switch was your problem on the truck! That was one of my first posts here on the forums. :)
Okay, now we are having a problem with stalling and no-start condition on an Iroc? Are there any engine codes being stored? If not, and since you recently replaced the fuel pump, I am thinking the fault is related to the fuel system, specifically the new fuel pump. It is not uncommon for these to fail out of the box. Especially if not properly installed and primed. Did you replace your fuel filter when you did the pump? If not, and it was clogged, it may have caused the new pump premature wear.
Use a fuel pressure tester and check the fuel pressure under load (Parking Break, Wheel Chucks) and ease on the accelerator. If you can't reproduce the stall condition you may need to get creative and strap the pressure tester to the windshield with duct tape and watch it while taking it for a drive.
