coil harness problem when engine is hot?

My car has been randomly shutting off at the worst times. Let it cool off a while and it usually fires right up. Disconnected Accel box/ new MSD coil and it worked for a while. Now its really bad. I just noticed the contacts in the coil harness are black/burnt looking.
Is the combination of MSD coil & Accel box too much for the factory wiring? Where can I get a replacement harness? Thanks, Gary.

No, it's not...

Get some electronics cold spray and hose the ICM down when it starts acting up.

Or just go ahead and do the ICM cooling mod..
