Help please! My 90 accord is stalling. I have replaced ICM, ECU, cap rotor and wires. Plugs are 5k miles old... It will start, run for 10 to 15 minutes.. when its warm, somewhere in that range it will shut off, and the CEL will come on. When I bridge the service wires, there is NO code yet the CEL just stays lit. What should I try next please?

Replace the coil, which is likely breaking down under load (heat). I recommend replacing them every 120,000 miles or 10 years, whichever comes first. I presume you applied silicone heat transfer compound to the back of the ICM. If you didn't, you need to.

Ill find some silicone heat transfer compound... and I guess cover the icm in it? Never heard of that before.. the one that was in there lasted well over 100k with out any of that... but ill try. I just replaced it last night, and I have same issues, so worth a try. And If not that? What do you think would be my next taks? Thanks

. Replace the coil--this is likely the main problem.

. Apply a thin, even coat of silicone transfer compound to the back of the ICM. This link should help:
