Random engine cutouts

So this first happened about a week ago. I was driving to work, and stopped at a light and my engine died. It started back up just fine and has been fine until today.

As I was accelerating (around 35-40 mph) my engine stalled and started back up again by itself 3 times.

All of this happend with I had my AC blower on high if that might have something to do with it.

I have a 4.0 2000 with around 108,000 miles on it. Where should I start my troubleshooting?

Anyone?

Its also been really warm today, up into the 90s. Don't know if that could have anything to do with the engine stalling.

I took a look under the hood, and the battery cables seemed fine. The battery terminals were a little messy, but not really corroded messy, more like gunk/grease messy.

Anyone else have any ideas?

They pretty much need to be cleaned spotless, regularly on a WJ.

Ok good to know. I didn't know if the gunk was like a conducting goo or something. I'll take a wire brush to the battery terminals.

is your engine light on? try the key trick (flip key from off to on position quickly 3 times, then look at odometer) look the codes up on wjjeeps.com if there is any

Check engine light isn't on, and it doesn't give me any codes.

Question about cleaning the battery terminals, its it ok to disconnect the leads without a 'memory keeping device'?

yeah....it'll "relearn" itself and you probably won't have it disconnected long enough to matter anyways

Your best way to clean is to disconnect and use a wire brush to clean and have a shiny metal look. Also clean the terminals on the battery. Use a wire brush on those as well.

Alright, I cleaned the terminals so we'll see how the stalling goes. I noticed that the negative terminal was loose before I even got to it, so I made sure to tighten that up.

Alright, it has stalled(ish) 3 times since the battery terminal cleaning and tightening. (The reason I say ish, is because it didn't completely die, causing me to restart the engine).

Once happened when I was making a left hand turn the engine stalled(ish) for a moment, but didn't completely die. It felt like it downshifted and then shifted back up within a second.

Today It stalled(ish) twice while driving around 55 mph. When it did it, it felt the same as described above.

I don't know if this is related, but my ABS light is on now too.

Haven't had this problem on my WJ, but a friend of mine had a very similar problem on an older BMW. It would intermittently stall (mostly when going around turns and stopping). Turned out the wires going to the fuel pump had become a little loose/dirty, causing it to stall on abrupt movements.

Might be kind of a long shot, but thought I would mention it because it is an easy thing to check.

I'll check that out UPJeepster.

So, tonight it started, and then instantly died. Then it took it probably a good 15-20 seconds of cranking to start back up again.
