It's most likely that the fuel pump is worn out and needs replacing. It often happens when you run the petrol level down too low.

I'D GO for the GQ Nissan Patrol. It's tough, plenty of parts are available and everyone knows how to fix them. I don't have any real problem with the Jeep, though early ones were poorly built and rather rudimentary with a small cabin.

THE MQ is really getting a little long in the tooth, so I would recommend you think about a GQ, though you will find it hard to fit one within your budget. Going by your description of the sort of driving you will be doing I would advise against the Patrol. It sounds like a very expensive way of getting to the city, ferrying the kids around and going shopping, with only an occasional weekend away. Go for a regular car -- it will be better suited to your needs and be less expensive to run. If you must go for a Patrol, buy the 4.2-litre petrol GQ.
