2015 Takeuchi TB 260 temp goes up caution light turns on loos of control function, temp goes back down and gain control

Hello, I have a TB 260 that temperature gauge started to go up then the caution light came on and the controls don't work, then a few seconds later the go back to normal and everything works fine. After a few min it's just keeps dong it more often and don't have any codes that are active. Any ideas
