G'day this Nissan Patrol 3.0di is dropping power on acceleration and with a quick Tap on the accelerator pedal the power kicks back in but continues to keep droping out.

Yours may not be the same issue as ours, but worth checking. We had similar, and various Nissan dealers replaced all sorts of expensive parts to no avail. Son took it out for 10 minutes and discovered the accelerator switch was occasionally sticking. A bit of WD40 and it has been fine ever since.

Read this out to the mechanic at work yesterday. Straight away he said "accelerator pedal", before I'd read MH's reply to him.

G'day Ben,
A friends 3 L Patrol did a similar thing many years back & turned out the MAF (mass airflow sensor) in the intake was covered in soot.
He cleaned it with throttle body cleaner then the issue disappeared. After that it became part of his service regime & problem never came back.
Worth a try as its not hard to do. Plenty of video's on the internet.
Cheers
Stu

Wear and dust will wear the carbon track in the pedal/throttle position unit and if the LOSS is when only around one position, the most used position, then the wiper inside the unit may be losing contact with the carbon, similar to a volume control but most have three wipers for durability/life. Dust will wreck it and IF the vehicle has been swimming and pedal area wet the unit will suffer prematurely.
Obviously you can't keep accelerating so is it when you back off to normal the problem reappears? Any movement of the pedal will immediately alter the ECU signal and all would work/appear normal again until back to same.
Many can be opened for a look see.

You could try an electrical contact cleaner with a lubricant (Jaycar).

it's on acceleration. And I think also does it when cruising like down the freeways

Have a gq 4.2 we had a similar problem turned out to be dirty fuel which clogges up a little filter as the fuel enters the motor. Could be nothing like the problem but it definitely happened to us .Good luck.
