Power drop off on hills

RW I’ve just fitted a new lift pump and it’s made an enormous difference!

So I took my 90 300TDi on its longest trip this weekend (about 100miles each way) since I got it, mainly dual-carriageway and motorway.

After just under an hour, the revs dropped off to nearly nothing, when going uphill and dropping a gear tio get the revs up gave nothing (5th to 4th).

What I found was that cruising at 55+mph the revs would disappear going up hill (I mean gone not just drop a bit) and I would end up at 35-40mph and not able to get the power down even dropping gears.

Now, cruising at 50mph this doesn't happen at all (it seems), yes I have to give some revs on the hills but its only a small amount.

The question is why is it that if I push that bit too hard on the hills the power disappears completely?

The lift pump was changed a couple of months ago and for the entire of the return 100mile journey (on the same route) this didn't happen at all, did it all at the 50mph mark.

This happened to me and it turned out to be a seized turbo actuator, this may have already been mentioned but I have not read the whole thread. Squirt it with WD40 wiggle it in and out then keep it lubricated.

I've not had a recurrence at all recently (though not done any long distance either), could well have been the crud inside the fuel filter housing I cleaned out whilst changing the filter housing out (because the bleed screw was stripped on the one I took off...), will give it a good booting up a nice long incline this weekend.

Will have a look when I do the head gasket (hopefully May Day is a nice warm and dry weekend...

)

Actually turned fine , I assumed something got sucked into it though I found no bits and don’t know how anything could have got there . air filter is fine also

just a thought have had this on several old diesel cars and found fuel tank vent partially blocked. give it the beans up hill and if it dies stop and whip off the filler cap you will hear it breath in if it is your problem
