How long since the fuel filter has been changed.
Do that and if it still does it have the fuel pressure checked with a direct reading guage hooked to the test port.
It should read 40 to 44 psi at all times.

On the fuel rail near the regulator.
You might also check the vacuum line to the regulator and see if it has fuel in it, signifying a failed regulator.
