My hot tub (a sundance montego) is having issues with the jets. Right now they will not turn on when I press the switch. Also when I press the air button I just hear a “click” nothing

However

If I turn the circuit breaker off for about 5 minutes and then go and turn it back on everything will work fine for 2-4minutes and then I am back to the same problem. I know it is getting power because the display is lit as well as the light on the control box.

I have tested the voltage when they were working and get 220 on all the relays on the bottom of the control board but when this happens I have zero readings at all the relays (Pump 1, Pump 2, ect)

Some one please help me.

One time I also lost power like I was saying and everything was dead and without doing anything the jets came back on

It sounds to me like your breakers are tripping off that is why when you turn them off, and back on, it works (turning a breaker off and then back on resets them)... Why? You might have a bad pump, or perhaps the heater element is tied into the circut of the pump, is bad, and is tripping the breaker.
