First the series of events. I overcharged my stock battery, left it on my circa 1978 sears battery charger and cooked it good. (not in the car) So I wasn't surprised that it didn't want to hold a charge afterwards. One day soon afterwards, the car barely started but I decided to run down to the gas station anyway. Got there, filled with gas and not even a click. Even boosting the battery the car wouldn't start. I figured it failed internally from my mistake. So, a used battery to the rescue. Started and worked fine until last month. Since that time about every 3 or 4 days the car didn't want to start. Naturally I cussed the used battery and put in my race battery. It too had the same symptoms. So today I purchased a new battery, put it in the car and it clicked but didn't turn over. Then all the lights would light up with no click of the starter. Waited 30 seconds and the car started normally, ran 30 seconds and died. It appears I wasted my money on a new battery and tomorrow I'll pull the RCM to see what it looks like. It's truly strange that after the first "no start problem" I drove the car daily and raced several events with no recurrence. The MYSTERY name fits perfectly seeing how inconsistent this no start can be. Now I'm hoping it's the RCM that I know how to fix and not some unknown gremlin.
