Well looks like the 3V regulator is shot;
4.89 Volts at C-USB (no-load)
4.79 Volts at C-USB with ESP8266 (good board)
4.73 Volts at C-USB with GIGA at 5V ref
4.73 Volts at board 5 Volt Pins
0.537 Volts at board 3.3 Volt pins
Dang, just when I was having fun... LoL
Time to order another GIGA, I don't understand the only thing that was on the board was the GIGA Display which I've been programming as a Thermostat Display. It has 3 buttons and figures that is it.
Here is the sketch I was running.

/*
This example uses the Arduino_GigaDisplayTouch and
Arduino_GigaDisplay_GFX library to change the
display whenever it is touched, inverting the colors.
The circuit:
- GIGA R1 WiFi
- GIGA Display Shield
