My mu cut out and can't get her started again

[Shaneo]

Hi all, so I jump started my 1996 Isuzu mu UCS96 after getting a flat battery, got it going sweet as then after about 5 minutes of idling normally it just cut out as if someone had turned off the key, tried jumping it again but it just keep winding over, sounds like it not getting fuel. IV checked the obvious stuff like diesel in the take and fuse boxes but no luck, the primer pump was still firm so I'm assuming it's still got fuel upto the filter, any suggestions or help will be much appreciated, thanks

What is the battery voltage? If its not charging the fuel cutoff may of released at 8 volts

Not 100% sure will check it. would the voltage off the alternator not keep it open while it was running though?

Why did the battery go flat? A bad alternator wont charge

Alternator was new I think the battery was just on it finally legs! Ended up just being a faulty fuel cut solenoid.
