Replaced fuel filter tonight and there were traces of dirt in the bowl.
Car overran 3 times since, but is mostly behaving.
However, took it out for a drive and at the exact same places in the road, the car shutdown - so that is still not solved. Right hand 90deg corner when I go around it the car just drops to ~1000rpm and then eventually dies out. Ignition system remains on - lights on dash. However, I cannot hear the actuator and in-tank pump whirring - so something has cut them out.
After a period of a few minutes and cycling the ignition numerous times, the pumps and actuators kick back into life again and off we go again.
Would the HP regulator blocking cause the fuel system circuit to shutdown for a period of time - i.e. mechanical fault causing electrical shutdown. Or is it more likely to be an electrical fault causing shutdown?
The BSI faults are most likely phantom faults - based on wheeler's reply on page 1 of this thread. So that points solely at the HP regulator being blocked as the culprit?

Ignore the evaporator temp sensor, speed info fault & the brake signal fault. They are known 'phantom' faults & will be in nearly every RHY/RHZ engine you scan.
Although before ignoring the brake switch fault just confirm the brake lights are working correctly.
If you had a charging issue I reckon there would almost certainly have been other electrical symptoms, I'd say the fault you experienced would almost certainly be caused by P0190. First off how old is the fuel filter? is this a Bosch or Siemens system?
EDIT: Just checked & it turns out the alternator fault code is also a phantom fault.
Any ideas as to where I go from here?
Edit - should say that P1138 occurred before leaving for the drive.
Inside of fuel filter housing - you can see metal filings at the bottom and effect of cleaning it :
