We have a 2000 GMC 6500 454 engine. Truck will shut off, we turn off the the ignition wait for about 4 or 5 minutes. Doing waiting time, if you turn the ignition part way on, you can't hear the fuel pump, and if you try to start, it will not start . But after the 4 or 5 minutes, when you turn the ignition part way on, you hear the fuel pump, then it will start. It will shut down with a heavy load or even with out any load. It seems to do it more often when it's really hot out. It will shut down as much as 10 times.

Depending on the year and model, it may just be rusty- frozen on the hub. Sometimes you have to use a very large hammer to break it loose. But using a hammer may damage it beyond the point of being useable.
