Mk4 mondeo tdci cutting out
Discussion
Twice tonight my car, 2007 mk4 mondeo 2.0 tdci auto, cut out whilst driving along. First time the car restarted straight away but the second time it took a good ten minutes before it would fire up. Before any of this the car had been driving faultlessly and it was the same afterwards too. There was no loss of any electric either time, no lumpiness before or after, it was almost like I had just turned the engine off.
I phone for recovery the second time but managed to get it going so cancelled it once I had got home and speaking to the recovery guy he said it sounded like an EGR valve problem. He asked if it had started once it had cooled down a bit, which it did to which he claimed it was a common problem and a blanking plate with a hole in would cure it.
The car has about 175k but full ford history and was my dads car from new so I know the history of it and it's never had any issues before.

This problem is still occurring.
It will start from stone cold no problem at all but once it has run for a few minutes it just turns over but won't fire unless it has some help squirted down the intake pipe. It runs fine and pulls really well but randomly cuts out. No warning lights on the dash and plainly refuses to start afterwards.
No faults are coming up when a reader is plugged in. It's also had a new battery and a full service including the fuel filter. The service was at ford and all the advice they could offer was plugging it in.

I think I have got a bit closer with this.
As far as I know there is a pump in the tank that feeds the injector pump on the engine. The fuel lines to the injector pump were dry and I can't hear this pump priming (I'm pretty sure I used to).
The fuse is fine and with it being an intermediate fault (although now it just won't start at all) I'm thinking it 'may' be a wiring issue but a session with the multimeter will tell.
UNLESS! someone says that there isn't a pump in the tank on my car and the the injector pump does both jobs, in which case it may have to go to a garage.

And still it doesn't run!
There is no air in the system, cleaned the inlet butterfly valve and sensors because it was all thick with sludge (which now have fault codes), fuel pump solenoid is working.
Crank position sensor has been mentioned but surely it wouldn't run at all if this was faulty?
I have read about people changing the injectors, injector pump, everything and the problem still persists. Also the starter has been mentioned but again it does start with assistance and it also wouldn't be the cause of it cutting out while running.
It must be something pretty obvious I have missed.

I have had forscan on the car tonight.
309 bar on the fuel pressure when cranking
271 rev/min when cranking
The only fault code is 0464 which is the egr and thats in the boot so I'm cool with that
The strange thing is the car started up first time and carried on starting but this got gradually worse until it wouldn't start but it still had 300+ bar fuel pressue. It's been stood untouched since monday evening until and hour ago if that has anything to do with it?
One more thing, when starting the car, it only turns over in bursts of about 5 seconds at a time, any ideas?
