I want to go all the way back to your original post for a minute. When the truck stalls do the brakes lock up?

Could it be my fuel pump module or fuel pump fuse?

I was originally thinking fuel pump, but your description that the brakes lock up when it stalls is beyond anything I have experience in. When you say the steering wheel locks up, I suspect you are just losing power steering since the engine is stalled, making the steering wheel difficult to turn, but not locking it. The only way for the steering wheel to lock is to turn the key to the off position.

When you say the brakes lock up, do you mean it is difficult to push the brake in order to stop the truck, or do you mean the truck comes to a screeching abrupt stop when the engine stalls?

Okay, now I understand what you mean when you say the brakes lock up.

The only way to test a fuel pump is to hook up a fuel pressure gage. Some auto parts stores (Autozone) have these to loan out. There is a valve on the fuel line on the top of your engine that looks like an air valve on a tire, and probably has a small black plastic cap on it. You remove the cap, and screw the adapter on the hose that comes with the fuel pressure gage to the valve. Turn the key to on (without starting the engine) and observe the gage readings (you need two people to do this). Next, start the engine and observe the fuel pressure readings. We will compare those readings to what they are supposed to be and determine if you have a bad fuel pump.

you have to turn the key a couple times after you put the gauge on too, that lets the pressure out. i think the ls series is the same as the vortecs which is high 50'* key on engine off, and it should hold there quite a while of it drops off it may be the regulator
