Default Help!@# Car Trouble!!!!

Okay so the car died about a month back and wouldn't crank back. I replaced the opti with a brand new one from jason cromer. I noticed that the opti harness was corroded, but didnt have the money at the time to replace it. Bolted in the new opti and everything.. car fired rightup. 3 days later it stalled out and wouldn't crank back. I figured it had to be that bad harness so i purchased a new harness from gm for 150 bucks. Car fired up perfect. Drove it 10 miles, car stalled out again and now continues not to crank back. I am lost as to what it could be.

ignition switch? it cranks but no spark right? ignition switch sounds about right. cuz in my s10 when the ignition switch went out, it was a intermitant (sorry for spelling) problem.

I had the same problem on the Vette a couple of years ago Craig. It ended up being a bad ignition module on mine.
