Jeep will sometimes start and sometimes not

Hi folks I'm new and not a mechanic. I've gotta 2002 jeep wrangler. It has a new starter and new battery (also recently tested), fuel pump works fine. A jeep buddy of mine and my local mechanic has checked everything out head to toe, however sometimes it will fire right up and sometimes it will not. It will start and ill drive it 6-7 miles run in the quick stop and come back out to start it and it will try to turn over almost like the battery is dead then just go click click click like it is completely dead. I've turned the key off and on several times the all the sudden it will fire up like it was brand new. I've even jumped it and it won't even start with a jump it will do the same thing. I don't think it's the alternator not holding charge because it'll do it 1-2 times outta every 30 starts and when it starts it fires right up. It's almost like there's a short some where but I have no idea where. I've had the computer pulled out and checked and have had it put back in and the computer checked without any issues. It's very frustrating b/c I love to drive it but never know if I'm gonna make it home. There are days it won't do it at all and then all the sudden I can drive it to work 12 miles get in it 8 hrs later and it acts like battery is dead. Thanks for your help.

Same thing was happening to me. I would try to start it and it would have either little or no response. Then all of the sudden it would work. It happened intermittently. A jump did nothing either. I finally figured out I had a tiny bit of corrosion on the Positive terminal on the battery. Since I cleaned that off I've been good.

You could have some break or corrosion inside the battery cables. I would replace them and start there

Yep that makes me think battery connection problem. Cable or dirty/loose/corroded/bad battery connectors.

I did replaced the battery and put new terminals on when I put a new winch on it but I did that in the early summer and this problem is fairly new. Ill check it out and make sure everything is good. Thanks guys any other thoughts???

...I would spend a lot of time really going over ever inch of those battery cables, their end pieces, each bolt, nut or washer that comes in contact with them. Somewhere you have some thing preventing those cables from carrying full power from your new battery to your new starter.
If it weren't for you getting the occasional 'click - click - click I would look elsewhere like at some secondary wiring/switch issue possibilities..... but I'm convinced you have some deep corrosion somewhere in or at the ends of those cables.
Good Luck
