2003 Cadillac SLS

Tried to start my car it wouldn't start. Made an unusual sound. All the lights and other equipment was working. After turning the key bac and forth it started and ran for a few minutes and shut off. Again after turning the key several times back and forth it started I want to know what are some causes it would do that

The not starting is somewhat basic in nature, but the stall and not starting adds complexity. It is possible that you may have problems in the ignition switch. Another concern may be poor connection at the battery, or perhaps at the ground cable that connects the engine to the chassis on RF up near the generator.
