Answer
I would have to go with possibly a failing fuel pump in the fuel tank or the rubber hose that connects the pump to the fuel pickup tube in tthe gas tank is loose and sucking air when the fuel level gets below the level of the pump and tube.

The fuel is what keeps the pump cool and when the fuel is low the pump is not being cooled and has a tendency to overheat and slow down thus low fuel volume and pressure.


What you need to do is put a fuel gage on the fuel rail and tape it to the outside of the windshiled when the fuel gets low and drive it while watching the pump pressure.
