I still can't figure out if the two events are related or just coincidence. We did feel around just like that because my electric fence is the same way, touch it with thick rubber shoes on and it's like the fence isn't working... touch the ground with your other hand and it zaps.

You don't have a short, it would break the breaker.

It sounds more like a open line, maybe one of the horses kicked it apart and it made a buzz and spooked them.

Trace your wiring down from the breaker to the outlet, you also could have a bad breaker on that line, they go bad sometimes.
