Had this on worn dry prop shaft splines. Easy to diagnose as there was side to side/up down movement.

Are you sure its not misfiring? The only fault i know that always resets when you turn the engine off is the notorious oil in red plug thing. Easy to check, its the red plug that goes into ECU next to battery.

Remove the earth strap from the battery to the chassis (or body i think its chassis) and clean up the surfaces, refit. Remove the strap that goes from the starter to the chassis (probably only chassis end is required) and clean surfaces and refit.

Good luck with it.

When you turn the key and hold it in start position how many times does it click?

Thing is..... If you turn the key and it only clicks once, it is the starter solenoid sticking. If it clicks over and over again then it's just not getting enough power.......

Yeah i know ive had one for years.

It wouldn't get in as the plug fills the hole in the sump. This is something out of the engine i think, but i have no idea what!

But they are not as effective off road, plus they don't look half as cool when you bolt them to the back of your landy.

If it's the handle sticking so you can't pull it then as said wd40. Take off the LR badge with a screw driver and spray it through there whilst working the handle. If its the lock spring then thats a different matter..

It probably isn't the injection pump. Take it for a spin without the caravan, do you get a lot of black smoke? If so it is likely just an intercooler pipe or something.

The spray (silicone spray) makes them lovely and bright and black again, but lasts a couple of weeks.

If i knew what jugglery meant i might have more of an idea, but the only thing i can think of is the steering shaft UJ's. By lifting the body you have increased their angle, so any wear in them will be more noticeable. Does the steering have tight spots in it when you turn from one lock to...

lol

This is nearly always UJ's. To check properly you need to ensure there is total slack in the drive train. Take out of gear and take handbrake off. Also select neutral on the transfer box. You will have to chock the wheels if its not perfectly level! Underneath make sure each prop can be...
