Just to update this in case it helps anyone else,
Occasionally my 2015 4.4 AB would stall at slow speed. No fault codes but then it showed code P0088-17(6C) Fuel rail pressure too high - general electrical failure. I spoke with LR but they had no idea so i googled it but again nothing but the code came up on a Russian site. The site mentioned Technical Bulletin LTB01083 which descibes my issue exactly. LR produced a repalcement part which cost 20stg and takes about 15 mins to fit and resloves the issue.
Below i have posted the procedure as described in the technical bulletin

SECTION:
303-14
SUBJECT/CONCERN:
Engine Hesitation/Stall At Low Vehicle Speed
MARKETS:
ASIA PACIFIC; EUROPE; OVERSEAS
CONDITION SUMMARY:
SITUATION:
A customer may express a concern that at low vehicle speed the engine hesitates or stumbles. In some circumstances as a result of the low vehicle speed the customer may report that the hesitation or stumble has resulted in the engine stalling. The engine will restart by cycling the ignition.
If the engine has stalled the customer may also express a concern that:
• The Touchscreen has changed and is now displaying the 4x4i – Terrain response/4x4 information.
• 'D' is flashing on the Transmission Control Switch (TCS) and Instrument Cluster (IC).
• The charge warning indicator is illuminated.
A technician may find Diagnostic Trouble Code (DTC) P0088-17 (Fuel Rail/System Pressure - Too High - Circuit voltage above threshold) stored in the Powertrain Control Module (PCM).
CAUSE:
Intermittent electrical connection. Suggested customer concern code MU4.
ACTION:
Should a customer express this concern, follow the service instruction below.
PARTS:
NOTE:
The glue lined heat shrink can be obtained from the harness repair kit (part number 418-104). They can also be sourced locally and claimed by ZZZ001 at a value of £0.75 per repair.

COMPONENT LOCATION
NOTE:
Some components shown removed for clarity.
E209715
The illustration shows the location of the fuel pressure sensor electrical wiring harness.
SERVICE INFORMATION:
CAUTION:
It is important when completing wiring repairs the appropriate equipment is used.
For instruction on the repair of wiring harnesses see TOPIx Workshop Manual section 418-02 Wiring Harnesses - Wiring Harness Repair.
SERVICE INSTRUCTION:
NOTES:
Some variation in the illustrations may occur, but the essential information is always correct.
Some components shown removed for clarity.
Removal steps in this procedure may contain installation details.
Disconnect the battery ground cable (see TOPIx Workshop Manual section: 414-00 Battery and Charging System - General Information - Specifications).
Remove the left air cleaner (see TOPIx Workshop Manual section: 303-12E: Intake Air Distribution and Filtering - TDV8 4.4L Diesel ).
E209719
Remove the Dynamic Response fluid reservoir retaining bolt and place the fluid reservoir to the side.
Torque: 5 Nm
E209716
Remove the retaining stud to allow access to the fuel pressure sensor electrical connector.
E210656
Remove and discard the fuel pressure sensor electrical wiring harness conduit.
E210658
Remove and discard the fuel pressure sensor electrical wiring harness.
E210659
Locate the blue/brown (BU/BN) wire in position 2 of the electrical connector (CW11-W1) on the engine wiring harness.
Cut the wire and prepare for a splice connector.
CAUTION:
Make sure that the wire labelled '2' is the first connection to be made. This wire has been labelled as there are 2 blue/brown wires in the link harness and they must not be interchanged.
E210660
Locate the wire labelled '2' on the fuel pressure sensor link harness.
Prepare this wire for a crimp connector.
E210661
Install the fuel pressure sensor link harness.
NOTES:
On all of the wiring connections to be made the heat shrink must be installed before the splice connector is installed onto the wire.
Do not apply heat to the heat shrink in this step.
E210662
Install the heat shrink onto the blue/brown (BU/BN) wire of the engine wiring harness.
E210664
Install the fuel pressure sensor link harness to the engine wiring harness with the splice connector.
E210663
Position the heat shrink over the splice connector.
Using a suitable tool, apply heat to the heat shrink.
NOTES:
The remaining 2 wires on the fuel pressure sensor link harness will require cutting to an appropriate length. They should be cut so the splice connectors are staggered along the length of the repair.
The colors of the fuel pressure sensor link harness are the same as the engine wiring harness.
Repeat steps 10-12 on the remaining 2 wires of the fuel pressure sensor link harness.
E210665
Secure the wiring harness with tape provided in the fuel pressure sensor link harness kit.
E210666
Cut the wiring conduit supplied in the fuel pressure sensor link harness kit to a suitable length to cover the wiring repair..
Install the conduit as shown using the tape from the fuel pressure sensor link harness kit.
To install, reverse the removal procedure. 2015 4.4 AB
