L322 stopping evertime I go out

Hi guys l322 04 plate keeps just stopping in of course the stupidest places .. if I look at the diesel pipe when it does there's no fuel there if I take the battery lead off and back on it fills up with fuel again till the next time .
Any of you smart guys out there any ideas
could it possibly be a dodgy relay or something i don't wana go out with now its embarrassing
lol any help would be appreciated

A good place to start is the low pressure fuel pump.

Have a live data diagnostic read done, to determine the fuel pressures on the low and high rails are acceptable.

Thank you I'll try that what reading should I see

Low rail I'd expect to see around 300kpa, maybe more at full power.
High rail should be around 25,000kpa at idle, and up around 140,000 at full power.
