United Kingdom 2015 Range Rover Vogue SDV8 Montalcino Red
Engine cut off while driving and not only

Hi all, I'm new to this forum so please excuse me if about this were discussed else where.
O own a Range Rover L405 4.4 , year 2015 and i facing next big problem ,
The car started with next problem : revs were playing but not all the time , ( only sometimes ) . After that when i was driving the engine showing fault and it stoped working , (every time i have to pull over and start it again) . When we read the fault codes showing FUEL RAIL PRESURE SENSOR.
We've changed almost all FUEL SISTEM , started with both rail sensors from Land rover dealer and NO ANY CHSNGES, after we changed new Hight Pressure Fuel Pump (New from Bosh) ,
then we discovered small Micro Pieces of metal in the Fuel tank and we cleaned it all and changed the Fuel pump from the tank.
Finally i thought that thats it , problems are sorted but...
I driven it about 2 days and it started again revs to play ( but not all the time) and also it started more often to cut off engine on the Motorway or whenever i'm driving.
The engine usually is working as its should and when i waiting at a trafic light or in a trafic the revs start playing and the angine just stop working .

Please if someone know why this is happening or has the same problem please give me an advise because we don't know why it does that.

I'm sorry if something isn't explained as its should but tried to explain with own worlds.

Thank you.

What engine fault codes are stored when it stops? If none then the crankshaft position sensor may be faulty, easily confirmed by logging engine RPM whilst idling with a diagnostic tool which will show momentary 0 or very low rpm.

Have you changed the fuel filter…if you have had debris in the tank/pump the filter could be blocked leading to fuel starvation and limited fuel rail pressure. 2012 tdv8 Westminster arrived Jan 19 gone Dec 23
