I had some time to work on the car tonight after a cruise in.

With engine hot and starter not spinning fast enough to start the car;
1. unplugged coil wire - no change in starter speed
2. Voltage drop test w/engine hot
- 12.8v at the battery (static)
- 10.8v across the battery terminals when cranking
- 6.8v to 10.8v w/red DVM probe on starter cable and black on starter stud. The reading was jumping back and forth between the two readings. crank speed was also fluctuating.

I am getting closer to finding the problem. It must be a connection problem in the battery cables. I will get serious this weekend.
