Hows your fuel filter? Have you done anything to the engine before it started doing this?

Just in case it has a vacuum leak you can easily say yea, or nay, by putting your hand over the top of the carb, while it is running. If it smothers and dies, versus continuing to run, then you can say no to the vacuum leak theory.

Does it have an HEI? I had a problem that arose after changing my vacuum advance. Short version: the wiring inside the distributor which fed a signal to the pickup module, would break when I let off of the gas.....which caused the "breaker" plate to move a little bit, and just enough for that connection to break. R&R'd the HEI with a rebuilt and no problemo.
