So I just recently picked up this car and it will run fine for about thirty minutes and then stall and have issues restarting until it cools back down. I've pulled the cel and it has codes 14, 21, 27 and 28. I know the last three codes are for the o2 sensors, I also know that code 14 is the igniter circuit failure. I'm trying to figure out what is causing the stall issues, I've swapped the ignition control module with one from the junkyard and the issue persists. Would it be wise to replace the ignition coil next or look into the ecu as the culprit? Thanks in advance for any help

Once started up, maybe after some time the igniter coil begins to get hot and fails to send spark?
I had the same problem on an old 94 Toyota tercel and the issue was the coil.
This problem persisted until eventually the coil stopped working. If you can remove the coil, autozone can measure the resistance for you (did this for me back then).

otherwise you can get an ohm meter, check the digital gs300 manual for the coil's acceptable ohm resistance, and measure the coil yourself.

I think that might be the case because the ignition control module is getting pretty hot. But why is this happening, it's doing it no matter which I've I throw on it. Also once it stalls, changing the icm doesn't resolve the issue. I think I'm gonna pull the ecu and check it later tonight

Turned out a few of the capacitors had leaked. I ordered new capacitors and once I get them installed I'll post if the issue is solved.
