Aha! that's a good clue.
The lockout switch is a simple screw-in plunger-type switch that is
physically contacted by the 3-4 shift rod (or lever, whatever). The
adjustment is very simple -- you stack washers around the base of the switch
to move it in and out. It sounds like yours could be making intermittent
contact due to road vibration. Or just the switch itself has a loose
internal connection.
It's located high up on the side of the transmission, on the left side of
the base of the shifter extension, facing up and back. In the blow-up in the
Moss catalog it is identified as the reverse lamp switch (which is actually
on the other side, although the switch itself is the same).
The bad news is, it's going to be very difficult to access, perhaps
impossible, with the transmission in the car.
