Oh, the sweet taste of success. I figured it out!! I had a bad connection in the plug (circled in red on the pic) at the brake switch that prevented power from being fed to the PTO clutch and the fuel cutoff solenoid (green traces in the pic) when the brake was disengaged. The previous owner obviously didn't find this problem so he installed 2 jumpers to put power in places that fed these components. With the restoration of the leads going to the seat safety switch I fixed a couple of days ago, all wiring is now back to factory configuration and the mower works as designed.
Thanks to StarTech and Auto Docs for providing the schematic and some guidance in the troubleshooting. Without that schematic, I could have never developed a logical plan to troubleshoot. You guys (and this site) rock!
Now that it's fixed, the 700+ page service manual should arrive tomorrow. Money well spent for any issues going forward.
