Change the fuel filter and see what happens. If the filter is clogging up it cuts down the amount of fuel
getting to the engine. When it stalls the filter is leting a little amount of gaas into the engine but not enough to let it run. While sitting the gas has enough gas to let it run until it runns low again.
It also might be a pinched or restricted line somewher, doing the same thing

Have someone turn on the ignition, but not start car. You should hear a brief whirlling sound coming
from the gas tank. If you do not check fuses. How is your oil pressure? Note: while running if the oil pressure drops below specified pressure while running the oil pressure switch will act as a fuel pressure cut off device. Check and see if you have juice to the fuel pump.
