Adding throttle increases both air and fuel. Give it enough throttle, enough fuel will flow to overcome a huge leak (I know this as this is how I "discovered" the 3/4" ID AAR hose was disconnected.) And yes, moving metering plate will add fuel, no air.
When it starts to quit, adding throttle does nothing? Can you hear or verify that both pumps are running? If you hold the ignition key in the start position after it starts, does the engine still die in 1-second?
Do you have mechanical fuel pressure gage in the fuel head/WUR loop or just the pressure as reported by the Unwired software? Are you sure you are reading control pressure, not "target" pressure?
Try unplugging fuel pump cutoff switch connection, top/back of CIS body?
