I have a 1992 Lumina APV 3.1 that after it reaches normal operating temperature and I drive it around for a bit, It will sputter and stall out. If I wait a few minutes it will start back up but quickly go back to sputtering. It will run fine with absolutely no problems while cold. I do have a few Ideas for the problem such as fuel filter(needs replacement anyway) and spark plugs. It was sitting for 4 years before I got it btw and had half a tank of old gas. I also have the feeling that the catalytic converter may be plugged.
