03 wrangler stalls intermittantly

So here's the thing. I bought my 03 about a year and a half ago. It's a really fun little thing to bomb around in and with a few minor changes it handles some pretty nasty trails. BUT for the last 6 months or so it has become completely unreliable. But not all the time. It's the weirdest thing I have ever run across. For some reason it will just quit on the highway. It'll stall out and sometimes even restart before i even have it pulled over. On the trail the other day it quit about every 5 mnutes so i turned it around and went down the hill. Then no problems for a couple hours. It quit again on me a couple times when I got back to town. Weird thing is. every time it quits it'll restart every time. Sometimes it'll conk out sitting in the driveway idling. The weird part is I have no CEL and have had it scanned twice and no codes. Whats even weirder is that it'll go weeks being perfect then all of a sudden screw up. Then back to normal. It's driving me nuts. I love this thing but am afraid to go any long distances with it just in case it doesn't restart..

Okay...only problem I've had with my 03 (automatice) is: bad gas, tripped the 'check engine light' and it ran REALLY rough until we burned it all out after adding bottles of drygas. Overheating (last month) thermostat and sending unit had been changed, temp guage was all over the place. When they refilled, left a big air bubble and it overheated going up major hills, lugged down and stalled out, wouldn't restart right off. Let it cool off, refilled and filled overflow tank-no problem. Now here's what sounds familiar...I had a big Chevy Silverado, 454, and it kept doing exactly what you describe-turned out to be the TCS (throtlle control sensor) that routinely 'died'. 65 down the highway, it would die...throw into neutral then back into drive, it would restart...always started up but would die idling. I do not know if the 03 jeep like yours and mine have the same thing...but it's a place to start. If you have had the codes read, just for giggles, go to someplace else (like Autozone, they do it for free) and get a second opinion! I found that my jeep mechanic would get a different reading than someone else (of course, his was usually right) but having a second and different reading means there can be errors!
And one thing several people suggested to me (wife's 94 grand cherokee limited was really acting funky)....disconnect the battery for a couple of minutes, then re-install and drive around. It will take awhile for the computer to 'reset' itself but it may clear out the problems! It could be something like the catalytic convertor sensor is bad or disconnected, blocked muffler, bad gas, fuel injection wire...almost anything that is less than $10 to replace but a heartache to find! And another problem we ran into-the gas tank 'pump' went bad and started doing the same type of thing-stalling out, restarting, etc.-until it just died going down the road and wouldn't restart. VERY expensive to have that one found...had to pull the skid, and the tank, ended up replacing the whole unit-don't bother try and fix it with aftermarket parts-been there, done that, lasted all of a couple days. It's the whole unit or nothing!
Good luck and report back what you find!

Question Fuel pump maybe??

I've had the thing scanned twice aside from having done it myself. When I did it it showed no stored codes and neither shop could find a code or anything either. When it quits while idling it seems as if it "runs out of gas" it doesn't just shut off, it bucks and runs really rough and then quits after quite a few seconds of this. I was wondering about the fuel pumb, but shouldnt it blow the fuse?
