Wow, very tough working condition for that Arm Chip...    
and interesting...  :)

May be you should use both power supervisor/monitor chip + external
Hardware WDT. => WDT "kicks" the CPU again if it does not power up
properly.

I've seen some AVR chips flash program-able for WDT always on after
reset.  (WDT default as on after reset)

Could you help eMail me your experience after the project??
Thanks in advance!
Regards
