How to make Pawn Sensing AI permanently follow player

My Pawn sensing AI is set to follow the player whenever AI see’s the player, however when making quick 180 turns the AI sometimes loses sight and stops following. What should I add to the Blueprint attached below so that once a Pawn starts following the player it will never stop following.

Wire the ‘On Success’ pin back to the ‘Cast To’ node. So that whenever it succeeds it is re-triggered.

Thank you!
