There's a well known fault with a faulty pressure-control solenoid inside the high-pressure fuel pumps on these. Your dealer should be very aware of this and should have correctly diagnosed the fault.

If Mazda won't cover this under warranty [and they wouldn't for an exactly similar case yesterday;] then get your local diesel specialists to remove the pump and contact Delphi [the UK concessionaires of these Denso pumps] as they can repair it at one of their three suitably-equipped repair centres.
