CHEVY STALLS AFTER PUMPING GAS

2007 Chevrolet Cobalt

Engine Performance problem
2007 Chevy Cobalt 4 cyl Two Wheel Drive Automatic 56,000 miles

It is really wierd, the check engine light cut on, went to adv. Auto. They said a loose gas cap, tightened it. Later that week I got gas, tightened cap, engine stalled, I recranked giving it some gas and went on my way. Ran fine. Light cut back on so I replaced the gas cap thinking it was loose. Put in fuel system cleaner, filled up tank, tightened new gas cap, engine stalled, gave it gas and went on my way. It only stalls after I have pumped gas, at no other time do I have this problem, the rest of the time the engine cranks fine. It has continued to do this for a while now. Suggestions?
