Dan---its does sound like instrumentation, or the setting for the fuel pressure are off. BUT------before you spend alot of time flying (
) trying to duplicate the problem, plumb in a known good mechanical gauge and check the pressure verses your GRT stuff. AND---just because you need something else to do, check the mechanical pump overflow tube for signs of fuel. HOPE not, but it wouldnt be the first time a pump would have a very small crack in the diaphragm and dump fuel, then stop.
Chances are its instrumentation, sender, wiring connections, etc, but check all of it.
