2000 gmc c6500 wont start

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.

Without a look under the bonnet sorry hood i couldnt tell you ,yes your getting power to the coils but it may not be sparking due to the immobilisor system as this breaks the earth return circuit ,i think the best bet is to ask a local mechanic to have a look for you ,also you havent stated the year of the vehicle as this can help to decide a answer for a question as vehicles do differ with different years of manufacture although the smae model

Cant get rotor off vehicle
