Hi guys,
I have just come back from travelling about 2,500km of WA's southwest and am starting to have intermittent problems with my 2009 Nissan Patrol GU VI 3.0L auto engine.
While on a beach, alone, on relatively soft sand my engine lost all power and cut out completely. Managing the panic, I switched off all electrics and the engine restarted after about a minute off bursts of turning it over.
I had another problem in soft sand 2days later where I could not get any power, not moving at all, in drive or reverse, 4WD or 2WD, but still could rev to 4000rpm in neutral or park. I fixed this again by switching everything off, waiting 30 seconds and starting again.
Driving
home the car lost all power and shut down twice, leaving me of the side of the highway. I noticed that both these incidents occurred either on or just after, reasonably steep inclines.
The car was packed with camping gear at all these times, but still within the GVM and was not towing.
The engine has no modifications, no exhaust, chip, blocked egr etc. and has just over 60,000km on the clock.
It has just has a major service with did not indicate anything of interest. I have since called the service centre back who request they take another look at the vehicle.
I just wanted to know whether anyone else has had similar problems with their 3L Patrol and if so, how they fixed it? I'd just like an unbiased opinion, before I start paying big $$$ for 'tests' and unnecessary replacements.
Cheers,
Nathan.

Hey guys,
Just a quick update, I got the car back from the service today.
Speaking with the mechanic, he stated that he actually worked on my vehicle when the previous owner had it. He said that when it was brought to him before, the previous owner had filled up both tanks with bad fuel, that included plenty of water and sediment. The fix included removing the tanks, lines and filters and cleaning and replacing parts to eliminate the dirt.
When putting everything back in, he installed a cheap aftermarket fuel filter directly from the tanks, to pick up any loose sediment still hanging around, to save replacing the Nissan filter which is much more expensive.
This aftermarket filter was replaced every 2,000km for a while then every 5,000km.
It turns out this is where my problem stemmed from. Not knowing that this filter was present, meant that is was not replaced in the last 15,000km.
It was found blocked today and and replaced, that car now seems to run perfectly and has noticeably more response and power.
I'm glad it was only a $60 fix, and cheap insurance for any future bad fuel!
Appreciate all advice and opinions given on original request.
Cheers,
Nathan.

I guess it might be hard to tell if its the filter or accel Nathan.
On my petrol 4800 GU I never replaced the fuel filters - but do backwash them every 50k or so.
