Do the horns work when everything else is shut down ?  If so, I would be
most suspicious of the control box.  Next time it happens, hop out with your
handy voltmeter (you DO carry a DVM?) and check for 12v to ground at both
the A and A1 terminals.  If one has power and the other doesn't, the control
box is definitely bad.

Be careful though, the terminals may be hot enough to burn you.
