There is a fuel pump prime cycle (2 or 3 seconds)when you turn the key to on and once you start the engine the fuel pump power comes though the oil pressure switch.No oil pressure,no power to the pump.maybe your oil pressure switch has become weak?I would use a scan tool and command the fuel pump on when it does shut off,just to make sure the pump can run,as it could be a bad pump too.Also when it does quit,if you turn the key off for 10 seconds, you should get a prime cycle by turning the key to on.Have someone listen at the gas tank for a fuel pump noise,which will be only 2 or 3 seconds,but will do as a pump running check.Next would be to check for power at the back at or near the fuel pump,power and no pump.replace pump.No power to pump,follow power back to the front through oil pressure switch and fuel pump relay etc.You can always add your own power to the pump from a power source the switches off with the key if needed bypassing the existing wiring and oil pressure switch.

Dear Don a,
I recently had a problem with my GMC doing the same thing, and it had the same transmission as yours.
The solutions for mine were the shift solenoids inside the transmission case.
Because I was driving a GMC van/motor home conversion, the local transmission shop could not fix it, so I had to do it myself.
I pulled the transmission pan, ( I had already purchased a transmission pan gasket and filter kit ) and found the two shift solenoids at the bottom edge of the transmission housing, and held on with 2 screws each.
I had to buy the solenoids at the local GMC dealer, they cost me $ 39 each.
I had the whole job done in 1 hour, and I am slow!
P.S. I found I had to tighten the transmission pan gasket several times because until I had the screws REALLY tight, it continued to seep oil.
God bless your efforts.

AIMING

  1. Park the car on a level surface, at least 25 ft. (7.6m) from a wall that is perpendicular to the ground surface. Make sure there is no excess weight in the trunk, unless you normally travel with that amount of weight in the car. Bounce the car a few times to settle the suspension.
  2. Measure and record the distance from the ground to the center of each fog light lens.
  3. Turn the fog lights on and adjust so the hot-spots (lit area of most concentrated intensity) are 4 in. (10cm) below the height of the lenses. The ADJUSTING screw is located at the top right corner of the fog light.

Yes you do have to burp the system. With radiator cap off (as opposed to the expansion tank reservoir which should also be off) the engine cold and the system almost full, squeeze the top and bottom radiator hoses sharply. Top up fully and replace the two caps. Bring the engine and water coolant to full temperature until the cooling fan kicks in. Wearing gloves, squeeze those hoses again with the engine running. You should feel the water surging. Turn off the engine and leave to cool. Remove the radiator cap and fill the system to the top. Replace the radiator cap. Remove the cap to the reservoir bottle and top that up to the MAX line. Job done and all the air pockets removed.

Heater switch might be bad so doesn't allow hot water to flow into the heater core. Also, there are doors that must move to channel heat into car, do you hear sounds when moving to Heat? Finally, heater cores tend to plug-up, so might require new core or power cleaning of radiator system.
