As Nodge says…
Hello?
Please?
Thank you?

C’mon, it really is a friendly bunch on here and there is a wealth of knowledge available, but dont don’t expect everyone to leap in on that opening!

I notice you say it ‘sometimes’ cuts out and then won’t restart.
Possibly the LP fuel pump on the way out? When it cuts out and you try to restart, can you hear it running (r/o/s wheel arch)

Unlikely to have a timing error, unless the crankshaft has broken.
If the ECM had failed, it wouldn't start at all.
Are there any codes listed?

If you had a dodgy pump that wasn't building pressure, but occasional built enough to start the engine - I recon it would go into limp mode rather than cut out if the pressure dropped. But it looks like pressures are OK.

Its the exhaust/cat blocked? If it was blocked, would it 'cough' when turning as it tried to start up rather than nothing at all?

Recon you must have a dodgy solder (in the ECU or a pin to the injectors maybe) or relay or summat.
