Yes. That's possible. However, I can 'reset' the cycle, at will, simply by
turning off the power via the circuit breaker.

When I do that, it pumps again, but, all the action is consistent with the
fact that it's running out of water.

For example, if I cycle it right away, almost nothing is pumped before it
shuts off; and if I switch it back on a bit later, more water is pumped.
The longer I wait, the more water is pumped before it shuts off (in a few
minutes).

This, I don't think, is the problem.

But, there are FOUR boxes (that could go bad).
1. One is the circuit breaker
2. The other is the no-load sensor (discussed above).

I'm not sure 'what' the other two a
3. One seems to be the pump controller itself.
4. I'm not sure 'what' that fourth box is.
