It is finally fixed. I replaced the electric pump with one for a 66 Tbird with a 428. Fixed the metal fuel line. Also checked the tank, it was already cleaned and sealed. Put in fresh gas.
I took it out for a long test drive. Let it sit a while at idle then drove again. Then turned it off and let the heat sink into all the components an drove it out again. All of these conditions are the same as those that caused the original stalls. The car ran fine through all of them without a stall.
I also checked the temps with an IR thermometer. Running; 160 on the radiator, 200 on the engine, 140 on the fuel line to the carb, and 105 on the fuel line into the pump, 195 on the engine. After sitting with engine off all these temps rose to the 195 mark but went back down when cranked up and running for a few minutes.
So whether it was the pump location, vapor lock or bad gas it seems to be fixed now.
I do believe I felt the issues with the distributor not advancing so that, the plugs and wires will be the next project.
Thanks for the help. This thread as wells as several others here were very helpful.
