I recently had this trouble on a DX80 system 18 mths old, first it had a bad flash card which I replaced. Then it started shutting off every day, a reset would bring it back but it would shutdown again in a day or less. I replaced the board & flash and had the same trouble. Yesterday I did a cold start and reloaded the database from a copy I had from several months ago. So far it's still running, it's been 24 hrs.
