I've been fighting this issue of and on for a few months now, but it's back . The factory radio will go completely dead, and then come back on after a varied amount of time, always after the car has been turned off and back on though.

The last time this happened, the next day the battery was dead, so I pulled it and had the auto parts store do a test and fully charge it. Tested good, and after the charge it issue was gone for over a month.

Yesterday the radio went out again, and still wasn't on after getting home 2 hours later, and this morning the battery is dead again.

I'm at a loss and would appreciate any tips or ideas.
