Could be the pressure regulator sticking on you. have that checked. The other thing could be the pump relay locking up on you. Pressure for that car should be around 30 - 60 PSI. if the regulator thinks there is more pressur in the fuel rail it will shut the flow off. after a while as it drains back it opens up. It's there to detect leaks and prevent a fire if the line breaks.Fuel line above fuel pump in the tank could be cracked and leaking disallowing proper fuel pressure.Change the fuel pump relay as it is sticking in the on possition.
