I have a cut out problem with my 2000 306 2L HDI, any help much appreciated.

Problem: The engine cuts out at higher revs.
#I can drive it even at 100kmph if I go through the gears and keep the revs below 2100.
#When I rev it higher than that while driving I can feel the engine shudder and if I reduce the revs then can keep it going. If I keep accelerating it stalls, the dash lights up with stop and an engine light stays on. I can re start the engine after turning the car off for a few seconds (while still rolling).
#It idles fine.
#I can rev it to 4000 in the work shop no problem.
#It seems to be related to heat, only happens when the car is hot (after 5 km of driving)
#I have changed the fuel filter and cleaned out the air filter, no differance.
#I have added clear fuel hose to look for air bubbles, there are no bubbles.
#I have added a lift pump to increase fuel supply to the injector pump, that did not help.
#I have taken it to the local Pug specialist, they said there are no faults being logged, they have no idea what the problem is and suggested I try an injector place.
#I have trawled forums for a fix and have not found one, EGR valve keeps coming up with similar problems but my car idles fine.
Any ideas much appreciated!

Try a Pug car forum, this despite google saying otherwise is not one for rare technical faults
