Thanks for the input guys. Yes, it is a bit baffling to me. I have read about a million times that the appearance of the ABS light is related to the OVP relay, but that said problem would produce an unmistakably rough idle or other driveability issues in almost all cases. That said, although I too suspected a low voltage problem (due to the excessive load on the battery and charging system at the time), my charging indicator light did not come on. I will check tomorrow to be sure that it actually works (lights up at ignition with no crank).

For the balance of the day, the problem did not resurface. It seems mostly to have been tied to the heavy load on the electrical system while idling. I have about a 45 minute drive home from the office, and it was smooth sailing all the way.

I will continue to monitor for this problem. If it resurfaces, I will proceed with your suggestions of checking the OVP and/or battery/charging system as I too suspect one of these is the culprit.

Thanks again!
