My RX580 Strix OC 4GB keeps crashing, after about 30mins of game time, the screen goes black and the card flashes white, but the PC stays on. its not overheating as the card only gets to 60C
 
I had problems with 19.3.1 and 19.3.3 crashing Shadow of the Tomb Raider after about 20 minutes. Rolled back to 19.1.1 (that's the most recent one I had the full installer still in my downloads folder) and haven't had any problems since.

Is this a new development on an old card that was previously running fine, or is this a new card for you?
