I have been playing it alot since release and have noticed that the game restarts after around 5-6 hours. I suspect that its due to the limited memory the XBOX 360 has.
Titanfall engine is Source - I also play alot of Left 4 Dead 2 (also Source) and the game restarts after some hours of playing due to the game being demanding in memory.
Also it is very annoying when you are doing well then you'll lose all your experience ☹️
