I think that if you do have two pumps you should check the one in the tank, sometimes the car will run as normal using the under bonnet pump, if this is the case you could be losing fuel pressure driving uphill or with less than a quarter of a tank

on the one in the tank did you just change the fuel pump or did you clean the little filter on the end of it on the bottom

I don't think its cutting the turbo. Its probably entering "limp mode" where the ECU will only let the engine rev so far/produce so much power. Probably because its sensed low fuel pressure. Can other things cause this though, such as faulty/irratic cam/crank/air sensors. You need to put a LR/Freelander specific diag reader on the car to see what it thinks is the problem.

Well, yes, but you seem pretty competent, and your scan tool does more than my crappy wi-fi one. Why not drive it with the tool connected until it acts up, then check fuel pressure readings?

K-Series is the 1.8 petrol. You say you have a Td4 diesel.
