Replace fuel pump
Easier than a Tahoe or Pick-up...Tank is in the rear, remove straps, etc., there you are...
Oil pressure drops and truck shuts off
I have to ask if you are sure the oil pressure drops first, or the engine stops first. The engine would stop if the oil pressure dropped below 5psi but only because the fuel pump would shut off. And it should start back up if that were the reason.
If something such as a relay or the ignition module is getting hot and killing the engine, it might have to cool down before it restarts. And the engine would stop then the oil pressure would drop to zero.
Fuel Guage Stops at about 1/3 tank...
With the chevy suburban (and perhaps some other GM vehicles), if the fuel gauge gets stuck at 1/3 tank, or if it's at that level and begins to act like it's out of gas (because it actually is), then you need to drop the fuel tank. Inside the tank is a square shaped box like area that the fuel sender and pump sit in. It is held to the bottom by three screws/pegs that should be held on by three washers that snap onto them. If you look into the tank and see that the square box area is loose and freely moving inside the tank, then you'll need to locate the washers inside, reposition the box onto the three screws/pegs, and snap the washers back on. Get a new gasket and put the pump back. You should find that the problem has corrected itself. That will save you the expense of buying a new fuel sender which is well over $100 on the after market.
Fuse box diagram
I would say that the power supply for the equaliser is not coming from the accessories or run wires of the ignition switch but from another source that is not controlled when you turn off the key.
