1) crank position sensor flaking out when hot? They will often do this before they fail
Measure resistance across terminals when engine is cold and when it stalls out. You should be able to reproduce the behavior just letting the car idle in the driveway. A/C off.

2) Outside chance fuel pump is cutting out on you. Only way to quantify it is to attach a fuel pressure gauge (or a real time data capture tool to the diag port) and monitor the fuel pressure as a function of time. If it suddenly goes out of spec and/or slams down to zero, that's pretty conclusive.

You actually should check the wiring that leads to the pump where it crosses into the tank. Might be a corroded connection getting bumped around. Especially if you cannot reproduce the sudden stall while idling in your driveway....

Remember, I am guessing.....
