ML 270 CDI - Cutting out on kickdown

ML 270 CDI - Car runs perfectly and normal kickdown OK but if you give it a large kickdown eg. when overtaking, engine cuts out competely which is a bit scary when you have no power steering. Injector seals have all been replaced and diagnostics say "Rail Pressure Monitoring" as a fault code.
Not sure what it could be. Help need please...

It is only when driving at normal revs and you want to give it a hard peddle to the metal kickdown that engine cuts out. And it cuts out at the 3000 rev mark if this helps.
Any thoughts out there because I am puzzled. Could it be MAF sensor problem?? (Was replaced 6 months ago)
