2005 Mustang shuts off while driving

We have a 2005 V-6 Mustang, twice while my wife was driving in the past week or so, her radio started acting up, volume increase and decrease and gets real staticy sp. The car shuts off, but when she turns the key, it starts right back up, and if the radio stays off the car runs fine. She says the clue to when it's going to happen is with the radio going bonkers. Alternator checks fine, ground cable checks fine. There has been a CD stuck in the radio (Shaker 500) that is constantly trying to eject itself. Could this be the problem, although it seems highly unlikely, I still have to ask.

Any clues or solutions will be greatly appreciated

IMHO, start checking for bad ground and continuity of the wiring harness...… my swag is it is either a oem splice or connector that has an issue...… you'll just have to purchase some basic test equipment and spend a weekend reviewing/learning the wiring layout of your car and checking at the pins until you ID the "spot". Second possibility is if you have Bluetooth (especially) connected to your phone, someone 9including a teenager) may be very well "messing with your wife" by remotely accessing the ECM/HVAC/Entertainment systems.... and yes, just about anyone who is tech savy or not can almost easily do this.

I have heard (read) that the Shaker radios, especially the earlier ones, can do all kind of flaky things; like constantly shuffling through the CD's or trying to eject them like you say. If you turn the car off with the radio on, the radio is supposed to shut off, but they don't shut off completely and can continue their antics through the night, killing the battery. A partial fix is to turn off the radio using the button, complete fix is to pull the fuse or replace the unit.

But that does not explain the shutting down thing -- that could be some wiring issue like Beechkid suggested, which can be a nightmare to find and fix . . . or, I think it might be a battery that is on its last legs.

If the battery is more than 3 or 4 years old, I would probably replace it as a first step. You can get them at Walmart for about $100 or so, and the swap is easy. That might not fix it; but it is relatively cheap and easy; and could save you from a wild-goose chase.
