The switch checks out good and when I bypass the switch at the 4-wire plug everything works fine. So it has to be a weak ground at the switch end. :(
I chased my intermittent stairs down to the door switch. When I pulled the the wires for the new switch through the door frame I found a place where they had been mashed in the door frame and had been occasionally shorting to ground.
Put in a new switch anyway, protected the wire that were previously shorted and steps have worked flawlessly since.
