Freightliner 108SD Electrical problems by year

Engine lights comes on and truck loses power and shuts down by itself. Truck was taken to dealer to be fixed, it happed arounf 5 times already and no one can find teh problem.

Sometimes the doors lock down when idling, parked, neutral. I was outside to unhook the trailer and because the doors locked down (idling, keys inside, all communication devices inside) I had to be on the unsafe no human being place from midnight till morning waiting for help. Electric door lock faulty, be extremely cautious when stepping out from vehicle, doors may lock down and leave you somewhere in hazard. Luckily truck driver paid attention me walking on the shoulder and stopped for help. Due to faulty doors lock system I was in dangerous situation, missed the next load pickup, spent hours and hours waiting for help and spent a lot of out of pocket money for locksmith.
