radio in my car works fine for 10min and after that dies

For all intents and purposes, car radios are disposable. It will almost certainly cost you more to have it fixed (if it's fixable) than to replace it.

Seriously, it's junk, go get a new one installed.

Or if you were happy with the features and sound quality, you can usually find a used replacement unit for whole lot less at your local salvage yard or by searching E-Bay.

Or, like top-posting Bob notes, junkyards are sometimes good. Don't let 'em rip you off though. Ford radios ain't known for their sonic purity. For many years Ford used the car's frame as the signal return ground from the speakers... not a good idea if you know anything about RFI, but it saved them the cost of 15 feet of 18ga wire, maybe $0.50 if that.

Times a few million vehicles.
