Ducato cutting out

[duck cat oh]

Hi all, my first time here
I have a 2005 ducato 2.8. Cuts out, doesn't restart immediately but does after you leave it for about a minute. I've scanned it and have got a fault code of p0191-fuel pressure control. Any ideas where I should be looking next? Any help gratefully received
Thanks for having me

Tuning boxes / remaps can thow this code first off. Secondly pressure errors are difficult to isolate as it can be regulator, sensor, wiring, lift pump failing / lift pump strainer blocked (check the low pressure side pressure), blocked filter etc.

If you graphs the requested vs actual pressure you'll have a better idea of whats happening. When was fuel filter changed last?

Thanks for your quick response.....I don't know off the top of my head so I'll check and change the filter if needed
Be back soon, cheers
