Game plays for 30 mins then freezes

Recently when i try and play a game, the game runs for up to 30 mins, and then i freeze.
I can still chat but the game is unplayable.
I have played this game for years with no issues.
I have not changed any settings as far as I remember.
I have the latest log file from my last game.
Can anyone have a look at it and decipher it, so you can give me an idea of what is going wrong?78a46289-fec7-473d-8b7f-b7a13d064aa2-game_23396113.log
