Wow, that sounds exactly like the problem I had with my EDP before I
found a bad solder joint on the board. 
Interestingly the same problem has just reappeared, I think, due to
poor earthing on a new rack case + very warm dry air and a nylon
carpet in my living room. At first I thought the unit was overheating
(again) but just putting my hand on the case to feel the temperatue
was sufficient to trigger a reset, ditto contact with the rack rails.

All this makes me wonder if certain SIM devices are more prone to 
static discharge than others (?)
