Hard starts and stalling

[joseph p.]

hi guys,would the yellow signal wire on the starter relay cause stalling if it were hanging on a thread of wire??I was changing the relay and I looked at the end of connecter and the wire was hanging on a thread,, literally,,,,went to inspect it and it just fell off.in that state could it make my car stall 2 minutes after warm up,and hard starts after the stall,changed plugs,wires, carb flow good,new solenoid,and new ignition box and ballast resistor,thanks for your attention.69 satellite 383 4bbl electronic ignition.

That only triggers the neutral safety relay for the starter. Nothing related to how the engine runs.
maybe check fuel tank venting?
I have has many fuel system issues in the past to where I just by-pass the original fuel system when trouble-shooting.
I rig up an electric pump to pull fuel from a gas can and feed the carb. If it runs good that way, but not with the original fuel system then I know where to start looking.
If the problem is still present, then I can start looking at other areas like ignition and vacuum leaks (assuming the carb is good.)
As for the carb, It could have a bad needle and seat or even a float that has a crack or pinhole allowing fuel into the float both can cause the carb to flood after a few minutes.
Bad or wrong ignition coil could overheat after some time also.
Could also be issues with the primary ignition power, bulkhead connector, alternator brushes and such.

A bad coil will run for 1-2 minutes then start stumbling and die (also a coil hooked up backwards)

Condition of fuel pump pushrod within length spec? Long topic on this in past comments. Search should find topic

I had one years ago that would go a lot longer. Guy I worked with who was a mechanic in the 60s was the one who figured it out.

Yeah, intermittent problems like that are the worst... coils are cheap (or free) i carry a spare one with me and points dist a slightly bad one will work til it gets good and warm then nothing.. wait a few mins and fires back up. a lot of fun
