I have also got a fiesta which had the same problem. It is to do with the battery being low on charge and all it needs is charging up, or you can get a new battery (recommended). If the problem persists I would highly suggest you try not to turn the car over too often using the same battery as you are draining the battery every time you attempt to start it up.
Last important thing! If you do happen to attempt to start the car while the fast pace clicking noise happens and the battery is completely flat you wont be able to lock the car! I found out the hard way. :)
