Troubleshoot for PTO 2 air solenoid fault, and for air pressure switch short circuit fault.The BHM supplies battery power on this circuit when the key is in the RUN or CRANK positions. Troubleshoot for a wiring fault shorting this circuit to ground or for too many optional circuits spliced into it that is causing the BHM to turn it off.

A scan tool will tell you what needs fixing and how much it will cost in order to fix that particular issue.
