would it work for 2 months and then stop all of a sudden if the gear wasn't
oriented properly? I would think it wouldn't work from the get go.

What if it was right on the hairy edge, then that edge broke off?

If you have been playing with the speed sensor because of resizing the tires
or swapping the gears, then that is the place I would start my search.
Loosen the bolt and reseat the sensor. You may need to rock the vehicle a
little to get the gears to mesh.
