Chase script. I added a FOV now he won't engage

My chase script was working okay until I added a fov of <30. Now he doesn't engage me anymore. Another thing I was wondering about - Before I added in the FOV and he was chasing me around his walking animation was really clunky. Very hit/ miss. For the most part he was sliding. Is this because I chose to slow of a walking animation? Or maybe I should slow down his movement speed?

Thank you!!
