What is the uP connected to? Any relays or solenoids?

you take a good look into the stack , it might be the reason. uncontrolled stack operation(s) may eat away RAM, thus causing problems.

Yeah, he didnt mention any battery (yet) so i assumed he didnt consider one. What triggered my response mostly was what he said, "blackout", and that means we'd better have a battery somewhere or the system is going down
