Sounds like you have a plugged vent hose or a plugged EVAP charcoal canister. You can try removing the hoses and blowing compressed air through it to clear it. I believe the charcoal canister is located behind the rear wheel on the driver's side, but I could be wrong.

On my older Pontiac, I had this very problem and the culprit was as follows: attached to the filler neck and between the tank there was a large diameter hose connection. It had become old and brittle and had collapsed to a small portion of its original opening size. I changed the hose, now no problems. I hope this helps you out.
