When ignition is in ON position, stereo works fine.
When I turn the car on, stereo shuts off. Sometimes it stays on for a min then shuts off.
Its wired correctly... Fuses are OK. CIG lighter works.

 

Prossibly the ignition switch.
When it turns off, wiggle and rotate the key and see if you can get the radio to come back on.

 

Dude you're a boss. I did exactly that and it works Lol.
