Mike, anything that causes the carb fuel bowls to empty would stall the car. One possibility, which I have encountered, is a weak fuel pump, or a leaking hose in the fuel line connection in the left rear wheel well. The fuel pump may be delivering enough fuel to keep the car idling forever, but when it is actually driven the fuel demand exceeds the fuel pump delivery, so that it gradually drains the fuel bowls till it stalls. You can disconnect one of the lines at the carb and connect a hose from the line to a coffee can, then crank the engine to measure the fuel flow rate (factory spec says it should deliver 1 pint within 40 seconds). 
I also agree that you should try a known good coil. Also, next time it stalls, just pull the coil wire and hold it about 1/4 inch from ground and crank the car to see if you are getting any spark. That would quickly separate ignition vs fuel causes.

I bought this car from a lady whose boyfriend tinkered with it but it barely ran. I replaced the gas tank, put the two rebuilt carbs on, new plugs, points, distributor cap and wires, rotor, and changed the oil. I put some Union 76  fuel (91 octane) in it and she fired up and sounded good. Put the timing light on it and set the timing. Took it out for a spin and it sounded, and ran great....for about two miles. The motor starting sputtering, like it was starving for fuel, it backfired twice, and was cutting out real bad. I pulled over and checked the motor. Everything looked good, nothing unusual. I let it sit for about a half hour then restarted it and it fired right up and sounded good. Drove off and was okay for about a mile then started doing the same thing again. I got it home safely and parked it for a couple hours. I restarted it and let it idle in my driveway for about a half an hour and there was no issues with it. I'm reluctant to take it back out for another drive until I c
an figure out what is going on with it. I'm not much of a mechanic. I got this car because I'm a 62 year old guy that used to have one of these when I was a kid. My 16 year old grandson lives with me and he and I have been working on this thing together and I want him to have it when we get done with it. Could the distributor vacuum be causing this to happen? I didn't replace it but replaced the hose to the right carb. Vapor lock? Trying to understand why the sputtering and spitting only happens after the engine gets hot. Maybe electrical and not fuel related? Looking for direction as to what I need to look at. Maybe the coil? I sure would appreciate any help you can offer. Thank you in advance. Mike Dick>>
