Just has to be moisture.  Ran it for about 15 or 20 minutes and shut down.  A half hour later it has the same symptoms again, constant alarm, no glow plug light.  Didn't try to start.  Going to cover with plastic today and put a space heater under it and see if I can dry it out enough to start consistently.
