2003 Audi TT Roadster ignition switch
 

My car quits running in the middle of the road when I take off for work each morning. It starts back up and doesn't do it again during my commute. I park in the garage so it's not that cold and I live in Seattle so weather shouldn't be an issue. All my digital information resets and has to be reset. My key fob now works intermittently to lock and unlock the doors (battery in FOB is fine) and car battery is brand new. Is this an ignition switch or larger issue?
