I have a 2000 Grand Prix GTP, and my car would start, but would stop after like two minutes of driving it, and it was the fuel injectors. Two of them were messed up and they were like 120 bucks apiece. It's hard to say what's wrong with somebody elses car without actually looking at it, but that and the transmission are the only things that have messed up in my car. Pontiacs have the worst transmissions ever, so beware.

It very well could be that the oil pressure sensor is bad or that the oil pump is bad. The ECM looks for a signal from the oil pressure sensor (or switch) and if it does not receive it within a couple of seconds after ignition it will shut the engine off. Have you checked for trouble codes stored in your ECM? I am wondering why you didnt change the fuel filter because water in the fuel can cause the same symptom. Fuel filters are made of a material that absorbs and allows gasoline to pass through it. If you get a slug of bad gas (an excellent reason to buy branded gasoline from a known oil company) it could be plugging the filter as soon as the fuel starts flowing to the engine. Another thing to check would be the fuel pressure regulator. If this compnent goes bad then your system may not be building enough pressure to inject the fuel into the engine.

Could be a bad ignition switch. See with a test light if there is power to the coil when key is in run position. If not trace back to switch, possible broken wire.
Some models have a module that needs professional test made. It used to be inside the distributor. If you have the skill, take the module out and to Auto zone for testing.

take your fuel cap off and then start it. if it stays running then the vent holes on your gas cap are plugged. or it could be your vent to the gas tank.

check cylinders, fuel pumps, spark plugs, battery, timing belt, the idle speed, etc...
