I'm leaning towards it having something to do with either the mechanical lift pump exhibiting a problem after getting fully heated up, or an air leak which only manifests itself after the fuel lines get fully heated up. I think it has something to do with heat because:
A.) It happens only after several hours which is time enough for the engine compartment to reach it's eventual maximum heat.
B.) The amount of time the engine will run normally after shutting it down, allowing it to cool, and restarting it is directly proportional to the amount of time it was shut down. (I.E. Shut it down for 2 minutes, get 15 minutes of run time. Shut it down for 30 minutes, get an hour of run time, etc, etc)
I think I'll invest in a Mr. Gasket Micro Electric Fuel Pump to put positive pressure on the lines at all times. Maybe this will either fix the problem or show me a leak.
