Hi again checked all the connections all seem ok so now at a loss as what to do next does this point to a faulty speedometer or to the speedo sensor because all of a sudden the display will come back on and all seems well for awhile before it goes off again.
Thanks Pete

If the speedo sensor was bad you would just see 0 MPH, as opposed to a blank display, so it really points to an intermittent power feed to the speedo or an intermittent fault on the circuit board. Do you have anyone that you can temporarily swap speedometers with to see if it follows the car or the speedo?
