Definitely sounds like valve issues...
I'm worried that somehow the head is being starved of oil - that sounds TYPICALLY like when an XUD has been dry of oil for a long time, the valves sieze down and make that horrible noise of running on three cylinders...
As soon as that happens it sounds like the ECU kills the engine though, it seems to realise that shit has hit the fan and kills the engine...
What's the max boost you've thrown at that engine?
I wouldn't be surprised if it's a shagged lifter, as Darren said, you sure it's got loads of oil in?
