My 94 Camaro lt1 randomly dies. It has been doing for a couple weeks now. When it dies it just shuts off, no noises or anything. So I replaced the ICM the other day and I drove it around for 20 minutes and it never died. But yesterday it died again, I thought it died when it would get to operating temperature because I check the temp gauge when it dies. But I took it to the shop and they let it idle and run for 2 hours and it never died, they even drove it around it still didn't die. No codes are throwing and no lights are coming on. I'm lost.. could it be the optispark?

Have you tested fuel pressure idleing and driving under various loads?
I would put a pressure gauge on it just to check.

Coil could also be your culprit. If you replace one you should also replace the other.

I haven not checked the fuel pressure yet, I will. Thanks for the ideas

More likely ignition coil, ignition module, or the Opti.
