Range Rover L322 TDV8 Fuel problem - limp mode

Hi

My 2006 L322 TDV8 consistently goes into limp mode after 8-10 miles of normal driving. If I pull over, turn off and restart it is then fine for another 8-10 miles. If I drive very carefully (ie keeping well under 2,000 rpm) it goes much further.

This issue first started after having a fried alternator replaced (on the way back from the garage).

There are two (relevant?) faults reported on my Lynx Evo - P0087-00 (fuel/rail system pressure too low) & P2290-00 (injector control pressure too low).

I have replaced the fuel filter and the fuel lift pump (in tank). I have eliminated it being a blocked breather pipe (by running with the left hand tank cover off !!)

I have ordered a Fuel Rail Pressure Sensor as that seems to be the cheapest thing that could be wrong.

Any ideas what to do next?

I think there are 3 pumps on that model with an in line one after the in tank pump that fails.

Thanks for your thoughts - there are two in the tank (the jet pump and the lift pump) there are no more between the tank and filter. There is the high pressure pump that feeds the injectors. The three readings on the high pressure system seem consistent and stable and dont change drastically as the error occurs. I'm beginning to think it may be the ECU itself...
