It can be much simpler than that. Maybe an I/O pin is left floating by accident (neither pulled up or down) and below a certain temperature, it gets toggled and brings the machine down. We actually had this exact problem, but it was the other way around: The floating pin was pulled the wrong way after a certain temperature was surpassed.

- raxxorrax 8y agoThis kind of problem almost made me go crazy once when developing a simple encoder routine. It is the absolute worst. "sometimes it does work, so a hardware fault is very unlikely and why isn't my software working if the sun is shining?" I reimplemented these routines countless times... Seriously, I was slowly beginning to think to look for a new career. Already getting angry again just thinking about it.
