Sounds like a computer issue but i may be wrong. test fuel pressure and spark ,go from there but you say it starts then stops i'd think the fuel runs out momentarily sounds like what you are saying

Key Fobs act strange. Replaced batteries, now one

The Key Fobs for the Buick LaCrosse typically fail after 4 years. Both of mine started off failing to unlock and then completely failing. I purchased 2 new ones on EBAY for $40 and had the dealer program them for $10. To buy new ones at the dealer is very expensive, about $150 apiece.

Engine wont turn over

This definitely sounds like the battery if your jeep is an 03 and the battery has never been replaced that makes your battery 6 years old most batteries average life is 3 years unless you have a no maintenance battery which will last a little longer. it should cost around 70.00 to replace I hope this has been of some help

Battery is not holding a charge, how long is the standard battery built to last? Also, after I put gas in the vehicle car has trouble starting again.

It's very possible that it's not your battery but your starter acting up. A weak starter will start a car when it's cold, but once you drive the car around and it heats up, it takes more power to start the car than normal, giving the indication that there's something wrong with your charging system when it's really the starter. I'd go to get your charging system checked out b/4 throwing in a new battery, only to find out it's something else. I'm guessing starter based on the limited information provided. Good Luck with your problem.
p.s. Most batteries will last at least 4 years

95 jeep cherokee not starting

Check the small wire on the starter to see if you are getting 12v there with the key turned. If you are, then it is possible that the starter (&or solenoid) that checked out good last year is not good now. If no power at small wire, then check neutral safety switch.
