i have a 94 z28 that it warms up and then dies out on me... i dont know whats causing it..

i had a short in the connector going to the icm, so i replaced the pigtail with the one from my old harness and it fired right up..

then it got to 160 deg and my SES light came on and it died and i waited a little while and it started right back up... so im thinking ICM???

but id rather know for sure before i throw parts at it... and is there anyway i can mount the ICM else where to keep it cool? i know about the whole ICm overheating issue, whts the best way to keep it cool?
