Honestly it really sounds like its a heat issue on the PS4. There are a lot of comments about how loud the system gets while playing the game so the fans seem to be working full bore just to keep the system cool. If a person happens to have their system in a game cabinet or somewhere where there's poor airflow the system probably overheats and shuts itself down to try and protect itself from damage.

Could it be shoddy programming on Biowares part thats causing a bug? sure, but it's not like its using a new game engine and you'd think Sony certification would of caught it since its there to try and make sure games don't brick their consoles.
