I've seen a few similar faults but think mine warrants a new post, but if you can point me in the right direction great!

Fiat 2.8 JTD on a Motorhome

Engine Starts and runs fine, but if you rev above 2000rpm it first sounds like it's not getting enough fuel and then cuts out instantly.

It won't restart again until you remove negative battery connectors, put back on and it starts again. We initially thought it was a bad earth made sure they are good.

The code that is shows is P0191 Diesel Pressure Test which I have seen in previous posts, and I've seen users replace nearly every sensor and still have the problem, I'm hoping someone can recognise the fault and point me and my mechanic in the right direction.

Thanks, but we have to disconnect an reconnect the battery or it will not start again. Seems they just wait and it's ok
