TD4 won't rev over 4K?

[TVR Beaver]

Hi Guy's... Never been on the Land Rover forum before but reading some post will be back soon....
But I wonder if you can help me with a problem I've noticed on my TD4 Freelander?
it's a 55 reg with 32K on it... LR serviced (sorrey I know!) from new...
I noticed the other day that I could hear the fuel pump when I turn the key in a morning before starting up... Don't think you could hear this before... not sure if it's related or not... anyway.. as the title suggests, it's now not reving over 4K... I know this is high anyway but on a couple of the hills on the way to work you just push into this band and it's like hitting the rev limiter.. soon as it comes back.. it's off again no problem... nothing showing as Engine fault on the dash... What do you think?... It's coming up to a service so will get a looking at... but would like to trace this before it goes in... May be a blocked air filter? don't think so.. little use and not dusty conditions.. fuel filter getting blocked... or fuel pump and it's new noise?... any thoughts would be appreciated....
.
Also.. it's now out of warranty so will be serviced at an indi... anyone know a good Landi place in the Leeds / Bradford area... I'm in Apperley Bridge close to the aireport... many thanks!!

Now only going to 3.6K?... must be the pump or filter I think... any more ideas??

If youre getting excessive noise from pump then I would say its working too hard so that may mean fuel filter/sedimenter is clogged with crap etc?
