As mentioned in my mod list thread, I purchased and installed an MSD 8456 distributor over the winter. I had it running fine the other day.
On Sunday, I had it running to warm up for hte 45 minute drive to a cruise/Dyno Day. Came out.....It died. It was as though I turned the key off. Tried to start it again, and all it wanted to do is turn over . Replaced it with my stock alternator....VOILA!
They're recommending I swap the stock module for the MSD unit, as they figure that's the problem.
