About 21:30, lost SPN1 data from near -- about the same time as the outage last night.  Hard to believe that the connector slipped again at just this time.  Vmote had decreased the entire day, but still was 12.4V at last report.  Unlike last night, the mote isn't sending reset messages.  Like last night, it doesn't respond to commands.  Guess we'll take a look at it first thing tomorrow morning (about 9AM).
