I went to go get some gas last night & after I dinished I turned on my LR2 & put it in Drive but before I could even get drive out the parking spot, it shut off. It had a similar issue a few months & I remedied it by replacing the fuse for the starter (F22 front passenger compartment) & did it yesterday morning as well however I just replaced the fuse and it did the trick up until later yesterday. I got it towed home & I went to go try a new fuse but it didn't work. It turns on and everything, ac radio all work but it just doesn't turn completely over.

 

Fuse was blowing for a reason, so that needs to be addressed. A bad starter could well blow the fuse, and if it's a 2012 that has never had the starter replaced it's probably about time.

Use a scantool to check for codes, but if that doesn't shed any light the obvious thing to do would be a new starter.

But I would check the connections to the starter first, and any big ground straps you can find.
