Thanks for your help and information. I'll see if I can take a look at those connectors.

Not 100% sure how I am going to proceed long term. My wife is leaning on the side of replacing the car. :-(

For now I am going to go under the assumption that the disconnected battery reboot was the ultimate solution. I also put a pair of pliers in the passenger compartment since you can not open the trunk of the roadster with the key. I can try the reboot if it happens again on the road.

Thanks again for the help.
