Rochester QuadraJet ... idle is fine... drive kills the engine

I have a 1972 Scout II (with a rochester quadrajet) that was sitting undisturbed for 6 years. I started it up and it ran fine in idle for up to 30 minutes at a time.

I worked on mainly cosmetic problems while the vehicle was in my driveway, and yesterday decided to take it our for a test drive.

At first everything seemed fine... I was lurching a little (press the accelorator and it would take a few seconds to catch) but nothing major.

After about 4 times going around the block the carb started to backfire every few seconds when I pressed the accelorator and the rig would die. I nursed the vehicle back into the driveway by starting the engine... Idle fine... But once I put it in "d" drive, got the same sputtering and the engine dying.

Is this a carborator issue? If so, what would you suggest doing to test/fix the issue?

Thanks.
