One thing to note. I hadn't driven it in a few weeks recently and when I tried to start it, it took awhile to actually tick over and I had a huge belch of grey smoke once it started. Been fine since though.

Rust develops inside the exhaust if left standing for any length of time, starting shakes it all loose and it bungs up the first true restriction, usually the back box.
Just the first thing that entered my mind upon reading your problem. I guess if you cant find any other reasons first (last resort) you could try running it without the back box.

Just another simpler possibility, your brakes are free aren't they?
May be worth a check to see if you can push the Jimny, handbrake off.

Previous to this it used to reach 70mph no problem at all, but now it struggles to get to 60 and slows down in the slightest of inclines whereby more throttle doesn't do anything.
I did think you were a new owner, excuse me.... Blocked cats often explain a sudden loss of power, the manifold cat is prone to failing and particles then block the second cat. Strip it down and inspect, I have heard of people just using a screwdriver to clear the cat body out and running it as is....

The grey smoke might have been a build up of oil in the cylinders whilst it was sat.
