Hi
The fuel pressure exceeded code is your pointer.
The car will require a new pressure regulator on rear of pump.
remove it and inspect shaft,it will be pitted causing a sticking mechanical issue.
The ecu is trying to earth pulse control the valve and the shaft is sticking causing a high pressure issue so the ecu,s strategy is to shut down due to excessive pressure at the wrong time.

Change 2 or 3 a month!
