No power/wont start-keeps clicking

What is your question?

was out of car 5 minutes last night andwent to go back in and would not start.. lost ALL power.. when tested and charger on battery, lights/radio would come on with the engine light. (like its in on mode but not yet started) and when I hit button again to start - lost all power. nothing .. but kept clicking

How long has your 2015 Ford Taurus had this problem?
