On my way to work my 1996 Chevy Lumina started sputtering like it was not getting gas yesterday. I was low on gas so I stoped and put gas in tank. This did not solve problem. On My way home this morning it was still sputtering, then 300 yards from my driveway it acted like it was not getting any gas and died. It will start but will not stay running. What could be the problem?
