stalls out when operating temp, replaced coil, mechanical distributor fuel filter, ignition control module, 136,000 original miles.

What is your question?

2017 I replaced coil, mechanical distributor, put brand new tune up, and fuel filter. ran for a year, then when get operating temp (not hot) stalls out, when cool off or cold would start, a buddy suggested to replace ignition control module, did so, ran till operating temp and was like only half cylinders were firing. ICM went bad, got a new ICM now will not run at all, had ICM tested checked out good, to the best of knowledge timing is correct. top dead center timing mark lined to zero, and rotary pointing to #1 plug wire. the only parts i have not replaced are the fuel pump and computer. i need suggestions?
