All better. I think the problem was at the starter terminal. It was pretty grimy and it had a half thickness 'Jam nut' on the stud. Some cleaning and a quick trip to the hardware store for a full size nut and the car is starting normally. I am glad this happened in my driveway on my day off with nice weather! Thanks to everyone who helped and special thanks to Dr. Bob for publishing the link to Wally's list. I will have to get after a few more of Wally's ideas...
