Fisher MM1 plow

The (3) wire isolation module for my Fisher keeps clicking and I loose the control light and operation. It seems like a relay resets in the module and the plow will work for a while again. The plow is on a 2012 GMC.
Any ideas?

That same isolation module controls the vehicle headlights and the plow lights.
Are you having a problem with those lights too ?
