Who is using a Rev-N-Nator ECU?

I had the Challenger out the other day and it would randomly die and restart. Tach would go to zero and then rebound and the car would run fine. I have a Rev-N-Nator ECU, about 10 years old. Just wondering if that could be the problem. Has anyone had similar troubles with one?

I have one, but no issues.  Had it for about 6yrs.

Yes good advice!  I had an intermittent start issue with my car sometime ago.  I had to wiggle the main harness coming from the steering column and it would fire right up.  I cleaned and tightened up the connections with zip ties and no issues since!!!
