A pound to a penny that it is the fuel pump relay has gone south. The fuel pumps used are very reliable and will generally outlast the car.
This is found up under the dash , easy to remove with 1 screw each side , then look around for the 3 relays on the rear of the firewall , usually mounted quite high up.
One of these is the fuel pump relay , which I think has a purple and black feed to it. You can swap this over for one of the others , in order to test it, then obtain a new one. Best go for a good brand which should last a long time.
Will try to dig out a reference when I have a few more minutes , but rushed right now.
