Where did my elec power go????????

New battery but once today when I went to start it all I got when I turned the key was a quick click and everything instantly went dead. Everything even including any interior light, clock, etc. Checked power to the post in the engine bay and there was plenty of power and same went for at the starter.
Got back in the car and tried again. Bingo! Started right up but had to set the clock and input the radio code. Now the overhead check oil light is on and I know there is oil in the car plus the same goes for the coolant level warning and I know it is topped off properly. Any thoughts?

Hmmm. Same model car, same color car and same state. Is it the rain???? Mine too ran rough at idle while it was learning how to again. I'm going to check some of the grounds and see if that produces any results. This happened right after I went over a nice speed bump and I heard a loud bang out of the trunk as if the battery was jumping around. I just picked this thing up and I haven't even checked to see how well the battery is secured.
