I'm going to assume it's a newer replacement style as it's much smaller than the old style regulators I'm used to.

What was happening was the it was spiking the voltage. The guage had bounced all over ever since I had bought the car, so I was not really paying attention to it. Just assumed it was the gauge as the car ran fine. However yesterday it was much more pronounced. It was jumping from 0 to the 30-40 range. I'm assuming that these spikes were causing the MSD box to go crazy.
