check your connectivity between WLC and AP. seems like some connectivity issue arise.

What firmware is this?

Software Version: 8.10.151.0

Remote into the AP and look at the logs.   

When the AP gets kicked out from the WLC, post the complete output to the WLC command of "show ap join stats detailed 2c:01:b5:c8:70:80".

Reboot the controller.
