Edit: I am an anus for not reading the first post fully...
Sounds like the pump is getting starved of fuel...
After reading you changed the filter, it's possible there's a blockage in the system somewhere. Meh, I'll leave in the filter pics as dirt just doesn't gather there
That filter did just 5k miles and all, Irish washed diesel problem in a nutshell!
You could also try the sender, in my old car it wouldn't rev properly until I took out the sender and cleaned it
I don't think your post says you did so...
Also, seeing as you have a 2.1, Lucas or Bosch?
