Engine starts smoothly then dies XJ358 2.7D

I have XJ358 2.7D. Suddenly went into limp mode, with check eTo receive from OFDRA members attending  further ideas and suggestions for the effective maintenance of  all OFDRA roadways.ngine. Would start after swich off, run for 10 seconds and then die. Repeatedly. .AA guys spent 3 hours trying to fix and then told me they'd done a reset - so no fault codes. Car has been at respected Jag specialists Powerbell in Taplow for nine months - have changed turbos, ECUs, refurbed injectors edtc etc. On Thursday workshop manager Andy said they'd run out of ideas and given up. Said in all the company's time (and they have Jag race team of their own) have never experienced anything like it.A huge problem for me, obviously.  Has anyone come across this before? Maybe have any ideas?
