Vibration sensitive?
Probably my first step would be to connect a voltmeter/DMM to the OD relay, and
take a test ride. If it shows that the relay drops out when the OD does, you
know it's an electrical issue. Then change the connection so you can see the
lockout switch at work. Again, if it drops out when the OD does, you've found
your culprit.
Might not be the switch, but the wires/connections to it. One of the Stags
would drop out for no apparent reason (although it was much more random) and it
turned out that the quick connect to the solenoid was very slightly loose. Not
loose enough to fall off, but loose enough to sometimes lose contact. So, if
the above test does show the relay is not being grounded through the lockout
switch, the next test might be to remove the tunnel and repeat the experiment
with the meter connected directly to the terminals on the switch.
