Driving along approx 35mph for no more than 5minutes when message came on dash Engine Failure and car ground to a halt. I am now waiting recovery car won't even turn over and I know I have a very healthy battery.Car had last full service and mot in January and had new air bags and struts front last week .checked oil ten minutes before this happened. Does anyone have any idea before RR take me to the cleaners yet again.

Turbo or crank would be my guess

Did the engine actually stop instantly? Any unusual noises? If it physically will not turn over, I'm with biketeacherdave, broken crank.
Oh I hope not 
Engine gradually slowed down , I had been running less than 3 minutes , so not even warm and it had a full service in January including all oils , new turbos fitted 18 months ago.

If you have diagnostics nows the time to get it out or if you know someone with diagnostics nows the time to tell them how much a great mate they are and remind them of that fiver they never gave you back!
The engine gradually slowing down could be inertia caused by the car moving, it may have stopped firing already but the gearbox would have forced it to turn over for a short time I expect. They don't really decouple a coast on the 6 speed trans.
Stick a socket on the crank pulley and see if it turns over smoothly, if it does you can rule out the crank issue but as Marjon has said, that's not a V8 "feature" generally, that's reserved for the V6 in the Sport or Discovery. If it's mechanically still in working order and rotates as expected, it's going to be a diagnostic time.

No idea I lost interest after the 1st failure when he wouldn't listen to common sense and sent it away for repair
It's going to be reasonable sized job and that is if they don't find anything else while getting into and out if it. There is sometimes the odd surprise 
Thats an ouch
.When it comes to something like this you need to ask.
1. Is the car worth it.(you don't say what year)
2. Is it only the turbos.
3. How much would a complete rebuilt engine+ turbos cost.
I cant really say but turbos are probably 1k each and its a lot of labour before other things are found.
Difficult position to be in I know and the cost could escalate as they dig in.
But that said I flew a "tophat lined" engine from the UK for the P38, it was worth more than the car, and still is, as it sits on the floor of my garage
.I suppose what I am saying is if its a keeper then maybe spending a bit more in the first place to guarantee no surprises might be a route to take.
Have they said why they think it happened?

Nothing said about crank failure
