Ignition switch issues?, Cranks but won't run with key Options

[trojanhorsepower]

So my car starts fine when I turn on the ignition and run the starter with a remote start switch, but not when the key turns powers the starter? This makes me suspect that the ignition switch is turning off the ignition while in the crank position. Is this a common failure point of these switches? or should I be looking somewhere else?

I have the same problem but with a different twist. My car (70 six) cranks and fires with the key in crank position but stops running in the run position.

This condition is most prevalent in cold temperatures. When below 40 degrees it takes multiple “crank -start-return to run-dies” cycles to get running. Each cycle it runs a bit better in run. Like it starts running on two cylinders, then four and finally 6. Once the engine is warm it will start normally. When it is in crank, it runs on all cylinders and will take throttle - but when the key is released to run, it cuts to 2 or 4 cylinders, stumbles, won’t take throttle and dies, until eventually (after repeated cycles) it “clears” and runs normally

When warm outside it still does this but to a much lesser degree. Typically one cycle of cutting out in run then starts normally, takes a few seconds to clear and then normal (same symptoms as cold but to a much less degree)

First thing I did was change the ignition switch- absolutely no improvement

Can’t figure it out. Fuel pump runs normally through all this. It is definitely ignition related
