I went to move my car today and she started up fine. Moved the car and turned it off. Went back to move the car 5 minutes later and when i turned the key NOTHING would power up (no interior lights, starter, radio, etc.)......tried a couple time and still nothing. There is juice at the battery. So I left it alone and went to do something else, came back again like 45 minutes later and the car started right up. Ive never had this problem before....any ideas as to what i should check (any relays or fuses and if so where are they located)
