Is only the blower cutting off? or is it not changing modes? or do you lose control of temp.?
Turning it off to reset could be a heat factor with an electronics assembly.

With the blower not running, it's hard to tell about mode but I don't think it is switching. The pushbuttons seem to do nothing. There seems to be no control of temperature. There is a little warm air coming out the vents but not with fan assistance. I think it is bringing in outside air over the heater core.
