Have a look at the four short rubber hoses that are connected into the intake plenum (large plastic doughnut shaped box, located under the engine cover) and see if there's any soot/oil/or splits/cracks, etc. They are a common weak spot on the 4.4 TDV8 engine and will set off the Restricted Performance problems, often at random but more usually under hard acceleration.
Do a search on this forum, there's plenty of info on this.

Check the hose to see if there's a split.
Have you still got the original hoses or have they been replaced with either the newer LR upgraded hoses or the silicone equivalents.
Maybe take a few pics and post them up, that may help with the diagnosis, but it sounds like it could be a culprit. It's relatively easy to replace the hoses. There's a good thread on here on the issue, but I couldn't remember the title of the thread offhand.
