Default Engine keeps quitting. Car talk level 1

If any of you ever listened to Click and Clack on PBS radio, you know that these guys can be pretty funny.
If one hadn't passed on, I'm sure they'd still be doing the show.
I would totally call them with this one, because it sounds like something right out of their show.

You can be click, or you can be clack, it doesn't matter. The object is to solve this puzzle. (no, I don't know the answer)
The winner will receive a fictitious, yet delicious chicken dinner, and a complimentary grocery sack of our finest post holes.


This is a 2000 Jeep Grand Cherokee. Almost everything has been upgraded or rebuilt on this by the previous owner, whom I'm unable to communicate with.

Occasionally, the car will be driving along and the engine just turns off.
The idiotlights and gauges reveal nothing. Turn the key off, turn it on, and it starts right up.
There's no choking, gagging, nothing. No warning of any kind.
The car can be going slow, or can be at highway speeds, it doesn't seem to matter. Smooth road, bumpy as hele road same thing.

The key has been jiggled in the lock with no nothing. The battery connections are good. The wires and terminals at the computer box are fine as well.
The shifter on the console has been jiggled back and forth. Nothing will replicate the engine shutting off.

Here's the real Cartalk clincher:

It only happens when she drives it.

Help!!!

Haha loved that show. I have guesses but as this is an archive of information site as much as it is a forum, I'll shut up and let the pro's comment.

Can't believe the obvious clik and clak response hasn't been posted yet....

Don't let her drive it!

LOL

My girl's Grand started doing this because of the transmission. The car would shut off at highway speeds and/or slow speeds. We decided to get rid of it instead of rebuilding the transmission... any hard shifting?

It sure could be. It has to be Mopar so it's 135$. Or try some simple an nearly free things said in the post above.


Check fuel pressure when it's acting up.
