AR,
Mine stayed off for several days, then came back on while driving to work. After work, stared up, it was off, but then in a short time it came back on. It repeated this for a couple of drives until I again engaged the cruise control before the light had a chance to come on.. and now it has stayed off after several drives. From what your error report says.. this sounds like a computer problem or program failure problem or maybe there is a board with bad solder joints like the RCM board that is causing the "Mystery No Start" problem. It would be interesting to investigate that possiblity if anyone has an idea if and where that board might be located. That might explain the coming and going of the warning light. Just a thought.
Keep us posted,
CaptDave.
