Strange hotend heater problem

one of my printer is suddenly showing this problem, it was wotking perfeclty for months, nothing was changed. Can it be power supply related ?
@paboman I am having the same issue but in my case I highly suspect a wiring issue - which I redo currently anyway. So you might want to check your wires going to the hotend heater as well as thermistor.
I agree, it looks like you have a problem with the temperature sensor or with the wiring between it and the Duet.
