92 Chevy Lumina Wont Start

I have a 1992 Chevy Lumina 3.1. The other day I was driving and the check engine light started flashing and it started to act like it wasnt getting any fuel. I let it sit for a bit and started it and drove home with it chugging a bit. I parked it and let it sit and then it started and worked fine. then I went to start it this morning and nothing wont start. im thinking it some sort of sensor problem because if I take the battery cable off and let the computers reset...it starts fine.....do you know what sensor it might be. Any information would be great. thanks

There is a chance it might be your O2 sensor. I would start there. GOOD LUCK
