If you have a GS model it's a two speed pump and the fuel pump resistor may be bad. The GS has an additional relay - fuel pump speed control relay which works in conjunction with the resistor.
If fuel is good then it's possibly ignition. Based on your symptoms it could be a crankshaft position sensor or an ignition switch and harness assembly too.

^We haven't had this problem so much where i work, but it's never a bad idea to make sure.
Step by step install-
1)Remove the right headlamp assembly.
2)From inside the headlamp opening, disconnect the pigtail.
- The wiring connector is located to the vertical fender brace forward of the fender well shield.
- The wiring connector is located to the top of the frame rail below the headlamp.
3)Remove the fuel pump resistor bolt.
4)Remove the fuel pump resistor.
Edit: I also just realized that if you're not taking it to a dealer there is a revised fuel sending unit assembly out for your car. Most non GM parts departments probably wont be able to see the change in part numbers. Its another possibility.
