   Ultimately (10 for 10 at least) the solution was replacing the coolant   
   temperature sensor. The computer didn't see it while it was failing,   
   but ultimately it showed up. Replaced it ($25 or so mail order) and so   
   far so good.   
      
   I'm sure there's a rational explanation, but I don't want to think about   
   this any more :-(   
      
   Life was easier with thermostats and heat risers. Plus you could throw   
   one pretty far when you discovered the problem out in the middle of nowhere!
