I think you're right that you've excluded heater and thermistor electrical problems.
Where are the hot end and PCB(s) in relation to each other? Could it be that the heat from the hotend actually heats the PCB and voltage regulators and so on?
Another thought is that maybe something else starts to happen at 80C e.g. maybe the hot-end fan tries to turn on, but it is shorted somewhere? Or maybe something else (the PSU?) is also gradually heating up and gets to a critical point when the hot end gets to 80C?
