with the George ,the flap can stick and leave you with no feedback to fuel requirement @ a given throttle position ,it needs to be free moving and snap closed quickly on the quadrant spring,posted recently about this and think the backfire story is a myth,mine has a vent disc and is sticking,the air flap is not a part easily bent,IMO its just wear as the air gate rubs on the lower cover plate when worn.
A guy on the bird has opened one up and proved that...good reading.
By all means check fuel pump function and check for a bad coil that is breaking down also.

Thank you for the guidance, it is greatly appreciated. When it dies, I will be driving along at 1-2k rpm, so the flap would not be closed. And, even if the flap was closed, the car would still idle, correct?
I hadn't considered the coil. Do coils fail in an intermittent fashion like this? If so, I see RockAuto has an NGK coil for about $15, so easy to just replace in case (or do I need a Bosch blue coil at like $65?).
Thanks again.

Hi. I experienced a similar issue with my 71 D-JET. Installed new fuel filter, new blue coil , checked timing again (as I had physically pulled the distributor to work on it) and no resolution. Inspected my points and found gap/dwell way off. Gap had slipped and was almost nonexistent. Car would start, run great for 20 minutes and die. I think gap would completely close off with hot dizzy. I reset the points and checked dwell and my issue went away. Of course I should have started at the points....
