69 400 FB - After 15 to 20 minutes the idle drops, engine surges, then stalls

This is a new problem and one I can't figure out. I can run the car for 15 to 20 minutes and then if I stop and idle for more than five seconds or so the idle drops, then the engine surges, and if I don't give it some gas it will stall. I can keep it running if I keep the idle up with the pedal but if I don't it will stall. Besides that the car runs great.

FYI, I have swapped carbs and I just swapped out my coil with a new pertronics flamethrower. I have a pertronics ignitor e-ignition. Any ideas?
