Wow, that's strange. I've got an '05 magnum with 42,000 miles. I had an issue with a fuse once. It was loose because I used it as a source for a power tap. Once I removed the power tap, the fuse wouldn't seat correctly. Every now and then my car would quit on me or not start at all. If you've done any mods under the hood, I'd start there and check your work. Make sure you didn't knock anything loose. (wires and such) As for the ticking, that's the fuel injectors.
