Update (in case it helps someone else someday): I was thinking about my new battery charger. I figured it probably tested the battery and when it failed to recognize the battery it ceased putting out any juice. So I connected jumper cables from my '95 pickup and voila, everything came to life.
So I immediately started the car, disconnected the jumpers and backed the car into the spare parking spot.
After shutting it off, I restarted it out of curiosity. That worked like normal. I did not drive it to work from fear of a recurrence.
The good news is that it is likely a 12V issue and not a high voltage issue or a computer issue.

i got the same year and problem in the last year replaced battery 3 times.dealers are cluless but love to bill you service calls.i find that if you start car every day in the winter dont let it sit for more than 3 days.i bought a battery jumper the size of a ciggarette package off amazon for 40 bucks lift front hood attach to car ground and red cap battery post and juice it it starts easily another thing shut all radio heated seats and heat and air fans off.some module is staying on and drains the 12 volt normal battery.

ive owned my 2013 c-max-sel with 80km on it now for 3 years other than the normal 12 volt battery draining from time to time when sitting still for 3 days or better i get great gas milage love the pickup and go, the build quality and its got all the bells and toys.but dont understand why FORD has not figured out the battery 12 volt drain issues.man just punch it in the net is full of complaints which doesnt help the image of ford.to be honest iam really leery of buying another electric vehicle from the company in the future but will go with one of the builds from japan. and i hate saying this for iam true blue but no fun getting stuck with service bills and the same thing happens down the road over and over....
