Breaker on the end of spa plug-in trips overnight. I can unplug it and plug back in, tub runs to it's 100 degree default settings. Will stay on and maintain all day, but overnight I will find the tub off and tripped again???? It is the Fantasy spa model from rec warehouse. Has the friction heat, no electric heat

I have had a few troublesome units over the year that did as you describe due to 'dew' overnight collecting around the tub and the increased moiture sent the motor of the circ pump "over the edge" iinto a grounded state. A leaking pump seal was adding to the problem. Once the seal leak along with the dew got high enough the GFI would sense the grounded condition and trip. Fixing the pump seal and drying/cleaning the motor fixed the problem every time. If you find any other leak sources around the pump you will need to fix them as well.
