No crank and No power what so ever.

My 2009 has started not cranking when I put the key in ignition randomly.  I get nothing at all....no lights, no dash instruments, no radio, no windshield wipers ...nothing... even the locks wont work.   The remote wont work either.  After slamming door, wiggling wires, taking battery out of remote....anything and everything...it will start right up. Sometimes the second key works immediately and sometimes it doesn't.  When it does start the clock is cleared but not the radio stations. And sometimes the clock will clear itself randomly.  Not a battery issue (new battery), checked all fuses, check alternator.....came across something that says might be a theft system fault or wireless control module....maybe.    Any possible ideas would and helpful and has anyone had this happen to them.   Other postings at least have the vehicles lights coming on....mine don't.   Vehicle is COMPLETELY dead when this happens.   Thanks in advance.......
