Jk issue

I have a 2012 that is having problems starting.. It'llturn over but after 3sec bogs down to a stall. It just started today and after a few try's on starting it will run just fine. But turn it off or stall and I have the same issue all over again.. Anybody had this problem?

How many miles and what mods have you done? Have you done anything under the hood? This could easily be a vacuum leak or MAF sensor issue.
If you start the jeep up and then give it lots of gas (keep the RPMs well above idle), does it still stall out?

I've read somewhere in this forum that if you tried to start your Jeep with a key that hasn't been programed, the engine will start fine, but after a few seconds it'll just stall out... Your key or whatever senses the chip in the key may be faulty... Not saying this IS your problem, but its something to keep in the back of your mind...

OP, call Chrysler/Dodge/Jeep customer care/Roadside Assistance @ 1-800-521-2779. You're under warranty. They'll pay for a tow back to the dealership to get this straightened out on their dime. Just make sure to specify your Jeep gets flat-bed towed. Towing with one axle on the ground can damage the transfer case and/or the automatic transmission if you're ATX.
This could be a batch of bad gas or a problem with a bad ground or any number of things.

Thanks for the help guys.. Called the Chrysler number only problem is I'm on vacation in Florida. They can't get me in till Thursday afternoon and i leave Saturday back to Texas. I'd hate to be stuck. (Well not really.. Florida is pretty sweet). Is there a way to reset? It seems like if I try to start it a couple of times it resets on its own and runs normal.

You can reset the ECU by pulling the negative battery terminal, pressing on the brake pedal a few times and waiting about 15 minutes before reconnecting the battery. But if you have any trouble codes, you could clear them in the process and possibly hinder the diagnosis at the stealership.

And the winner is Dillon... Didn't realize I had a chip in my key. It looks just like a valet key, went swimming in the ocean so I'm assuming I jacked it up... But it's a security feature that shuts the vehicle off... Thanks again for all the help, yet again this forum shows its usefulness.
