Drain all of the fuel in the tank out, refill with fresh fuel, and add the proper amount of fuel stabilizer. If you have old fuel, or somehow water has been introduced into the tank this is the exact result you will get. If the problem persists, MAKE the dealership repair it if it is under warranty still.
