Well, took a bit longer than I expected but I finally figured it out. Seems after only 200,000 miles it had a catastrophic bearing failure inside the distributor housing. This was causing the camshaft position sensor which is inside the distributor to contact the sensor pick up intermittently and wig out. Think I might just replace the whole damn thing with a rebuilt unit. Either that or I'll try to get numbers off the bearing and just rebuild the thing myself.

Thank you all for the advice and the PM's offering assistance.
