Check your Air Filters! I'm dealing with issue as we speak. I had to remove the Air filters, and slap the dirt out of them so that I could drive home from work. It happens to me all the time, especially if the filters are more than six-months old. You need to keep a small tool-kit in your car. These cars will leave you stranded when you least expect it.

Tool-kit I ride with:
Small Led flash-light
Screwdriver & torx tool set
Wrench/Spanner set
