Sounds like a master cylinder problem.I've had this a number of times in the past with many makes and models of cars and it's always been the cylinder causing it.The seals harden and allow fluid to pass them intermittantly.
Just out of interest,have you had any work done on the brakes recently.It can happen after you have had the pads changed.
