2000 Saturn LS2 Question: My saturn starts and run but stalls after a few min..It will not stay running

possible issue with fuel pump. can manual test by turning start key and stopping before it turns over. should be able to hear pump. short whirring sound from the fuel tank. this is your fuel pump priming the fuel line. if pump is strong, should last a second(2 sec.s tops), and then shut off. if it takes longer than possible fuel pump failing.
review when last tuned. it may be due.
rec. fuel system clean. ethanol treatment to 1 tank of premium fuel. ethanol blend in fuel causes build up in fuel system, combustion chambers, exhaust and will cause excessive wear to spark plugs.
rec. oil stabilizer treatment on next oil change. this will recondition seals and cylinders.

Had same problem. Check Heater Control Circuit Bank 2 Sensors-there are 2 of them. Also check the Mass Air Flow Sensor. A bad MAF will disable the car-trust me. If you replace only one of them, the car will still run rough due to bad readings on the gas/oil mixture.
