Thanks for the advice. The final issue was corrosion in the connector for the main bundle of wires going from the engine bay to the dash. The pins were cleaned on both sides and sealed with an electrical cleaner.
The symptom's of this issues were the challenge:
1. Gauges were erratic at idle and engine would die.
2. Sometimes the engine would not start, no power to gauge panel.
3. The wires to the kill switch were getting warm and sometimes blowing the ignition fuse.
4. Would not happen all the time.
I hope this help others.
