There was a note on Beaglebone Black that the newest version BBB version 6 has or'd the reset button and the power button to prevent a reset, now whether or not it is the same problem as posted originally, ho knows. But I had the same issue where I was ssh'd into the BBB for several hours and then it just stopped for no reason.
