Simply put, and from your description, most likely just a bad connection in

That was my guess too, but I'm unsure about the connection between the
breaker and the hot buss. I thought maybe the connection was good
enough to show up on the meter, but not good enough to carry the amps
needed. However, if the connection there were loose, the load on the
circuit would bleed off the voltage downstream of the loose connection,
and I wouldn't have 120+ volts on the breaker's wire lug, right??
