All the contacts are new since I replaced them just 3 months ago.  In
fact, I think I found the problem.  One of my butt connectors had not
been properly crimped. The wire was free to move and I think when it
got cold, the wire shortened just enough to come free.  I can assume
with fairly high confidence that is what happened.
