Finally, Finally got to the bottom of this problem, after changing the MAP sensor and the problem still persisting, I decided to do a run with the diagnostics still plugged in and do a live data test, it turns out that ford in there wisdom, have to admit it is impressive, have installed an overide system which means that if the engine gets too hot it cuts back the power normally around the 125 / 126 degree mark to save it cooking the head, it also turns out there's an issue with a spline wearing that connects the power steering pump to the water pump and hey presto problem solved, now just need to replace the offending part, thanks for the help and advice from various members
Might be useless information,but worth considering or giving to the mechanic/technician.
