Refercomments from donh54 and afloat, I 'third' the idea of low pressureside issues first.
Don't know if you have access to this info so thought i'd post it, below are some extracts from a workshopmanual I found online for the D4. The manual doesn't have the P2290 code in it, but Ifound someone asking for details of P2290 on Rrsport website, and itturned out to be their fuel filter.

pressuresensor tests, refer to the relevant
workshopmanual section. Check the low

Checkthe fuel pressure. Check the low
pressurefuel pump module circuits and
operation.Check for fuel rail and high pressure
fuelline leaks. Check for volume control valve
andpressure control valve DTCs and rectify as
necessary

- Actuator stuck open
ACTION:
Referto the electrical circuit diagrams and
checkthe pressure control valve actuator
circuitsand rectify as necessary. Check the
resistanceof the fuel pressure control valve. If
theresistance is not between 0 and 5.4 ohms,
installa new high pressure fuel pump (the fuel
pressurecontrol valve cannot be serviced
separately).Refer to the relevant section of
theworkshop manual. Clear the DTCs and test
fornormal operation. Refer to the warranty
policyand procedures manual if a high pressure
fuelpump is suspect

Hi, I have a 20011 Disco 4 (TDv6) 2.7l and had the same problem in Jul 16.
I also took it to Landrover Brookvale as my usual Landrover mechanic said he could not do it.
LR Brookvale originally quoted me $5200 to replace both pumps and N/S cam seal that was apparently leaking and could be changed at the same time.
After my heart palpitations had settled a bit they said they would look at an alternative. They ended up quoting for the same work using aftermarket parts for only $4K....including the car wash!!!! What a deal!!!.
My car was going into limp mode on a regular basis and I had no choice.
I don't see why they can't quote you for aftermarket parts and I am sure that the price has not gone up that much in the period since my car was repaired.
I also think that the comment about the reliability of the car and whether this is a design fault of Landrover that could be pursued through the ACCC is also worth investigating. Hope it helps.
Hi I have a 2.2 in a 2014 Defender.
I was towing my broken down 110 ( long story)and experienced the same fault as you were having.
This was when we left Glen Innes in the morning.
The low fuel rail pressure happened 6 times.
All while going up hill towing the load.
I just backed off for a little while and the fault did not reoccur.
My diagnosis was that the fuel was cold and the pump could not keep up with demand due to the load.
Or the up fuel pump needed to warm up to close the tolerances up.
Are you having these faults when cold?
I seriously doubt that both pumps have failed.
i had similar issues with L322 Rangie.
i am a mechanic by the way. I have replaced 2 low pressure pumps but never the H/P.
The low pressure pump satisfies primary fuel pressure switch and until that is satisfied the system will not operate.
you have nothing to lose by simply replacing the low pressure pump first as that is not difficult or expensive.
i even set up a pressure gauge on fuel supply from low pressure pump when I was trouble shooting the system.
Whilst I would always like to support other mechanics decisions the quote given to basically replace everything seems a bit like " if we replace everything it must be fixed"
It is your money Ralph!
I finally found a copy of the service schedule that supports what Tombie has mentioned and it's not new; I think I downloaded these files from this forum a couple of years ago.
As you can see the Arduous Schedule lists timing belts for 91k/4 years for early model years and 112k/5 years for MY14 onwards.
If you ask a dealer specifically about the Arduous Schedule they will find this info in the system but in my experience they don't get much call for it, which is fair enough when the vast majority of customers don't need to follow it and they'd be accused of unnecessary gouging even more if it was suggested.
Whether an owner deems their usage to be Arduous is their choice so it's not something to be forced on you or moan about, it's up to you.

Scott and Tombie, those schedules seem to conflict with what I was told when I purchased my vehicle. Mine has a "normal" schedule of 26,000kms/12 months. The type of schedule does follow your A,B,A,B, A, C etc. However I was told that if I put the car under "Hard" use (ie towing a caravan or lots of 4WDing, then the intrernal computer will automatically adjust the time period and/or kms traveled. My car came up with the 1st message at 20,000kms, with the message that the service was needed in 2K time. (ie at 22k not 26k). The 2nd came up at 41K, and the car was serviced at 43K. I do my own oil and filter change about 12K after the dealer service.
It seems that LR extended the standard service intervals to longer kms (not time) in the later D4s.
