Help troubleshooting a fuel? problem

I just bought a '92 cavalier.  It seemed to run well except once in a while, at a stop light, when the light turned green and I stepped on the gas, the car would act like it was in 5th gear (its an automatic by the way) for a few seconds and then it would be fine (I don't think it has anything to do with the tranny.. I just mean that it was bogged down and choking like it was in 5th gear).  Last night I was at a stop light and the same thing happened, only this time minus the fine part.  I found that the car idled ok, but as soon as I touched the gas it would start choking.  I put it in gear and idled it down a side road and almost made it to my work before it konked out completely.  I managed to start it again for about another minute (by this time it was idling pretty rough) while I looked under the hood, but I didn't see, hear, or smell anything out of the ordinary.  Now it won't even start for me.  The check engine light came on while I was idling down the side road.  I am hoping this scenario will give someone a clue as to what my problem might be? 

Thanks to anyone that can help.

Never mind... I ran outta gas.  Stupid gas gauge.
