How did you check fuel?
Hearing the fuel pump buzzing is NOT a check for fuel.
It IS a check for power to the fuel pump motor.
The pump can buzz but NOT deliver fuel.

When your engine quits, check for pressure at the rail as Chris said.
You should see a strong spray out of the rail Schraeder valve
being careful to keep from getting sprayed with gas. You don't need a gauge
to know there's no pressure there.

IF there's no fuel at the rail- Swap the Fuel pump controller at the main
fuseblock. It doesn't matter if the controller is new, I just had a new
KAE fuel pump controller (3.302.230) quit after less than a year!
HINT: Don't use the KAE controller, The one I tried was junk.

IF you get a strong stream of gas from the rail,
THEN focus on the main fuel relay over the driver side of the radiator.
When that craps out the injectors wont open.
