My wife's 2000 Jeep Cherokee with a 4.0 I6 and automatic transmission periodically stalls when accelerating from a stop. Fuel pressure is good and there are no codes. Any suggestions?

2000 Jeep Cherokee Stalling

Just had one of Jenns friends have a stalling issue with her jeep, don't know the year right off, but it seemed to do it after it was warmed up, ended up being the crankshaft sensor she said.

So far I have a new camshaft position sensor, crankshaft position sensor, oxygen sensor and spark plugs. I haven't been able to give it a final test because during a previous test the transmission input sensor threw a code and the transmission started acting up. None of the parts stores carry the transmission input sensor so I am waiting for the dealership to get one. I had to buy a scan tool in addition to the parts.

Does it stall right off idle? Or when its coming back to idle?

It stalls accelerating from a stop.
Maybe the EGR valve is opening too soon?...
You say stalls, does it stall and die or sputter and will idle again?
Can it be restarted if it dies? If no, how long to wait til restart?

It just instantly dies. It can be restarted immediately.
The stalling started a couple of weeks ago. Then I threw a code in Minocqua, WI 70 miles from home. I scanned at O'Reilly's and it said I needed a camshaft position sensor. So I changed it in below zero temperatures in the parking lot. The printout they gave me indicated that it might also be a crankshaft position sensor since they interact with each other. The stalling continued so I changed the crankshaft position sensor. I changed the oxygen sensor because it had 147,000 miles on it. When I was testing driving the Jeep I threw another code and the transmission started bucking so bad I did not want to drive it to town so I bought a scanner. It told me the transmission input sensor was bad. Even though I tried to stay away from computerized vechiles as long as possible it was inevitable I would be assimilated. Resistance was futile. I changed the spark plugs because they were due for a change.

Going to go with a throttle position sensor then.
Grasping at straws here but TPS seems like a possible issue.

My friend has had to change a few neutral safety switches on Jeeps and othe Mopar automatics...they can cause strange symptoms like yours as well as foul up the shifting of the tranny...
He never would have suspected that to be the cause,till he called a local dealer to see if they had an ignition switch and key in stock (he's had those go sour,the chip in the key starts acting up)--the parts guy asked him if he replaced the neutral safety switch yet--when he said no,he said I'd try that first--we sell a lot of them,and the symptoms you describe match up...so he bought one and installed it,and he hasn't heard anything back from the customers yet,so he assumed that fixed it..the trucks had no codes showing so he suspected a electrical power loss..he said it was no fun getting the switch on too...I think he had to drop the pan and connect wires inside it if I remember right..

I put on 75 miles today. It looks like the Ckerokee is fixed. Thank you to everyone for your input.
So..... What did you find that was the problem?

That is the problem with computerized engines where all the components interact. Sometimes it is hard to tell exactly what the problem is and sometimes it is a combination of components. I don't know specifically what the problem was but I am happy it is fixed.
Cool. When you get time you might spend some time checking all your ground connections and the wiring harness for chafed spots.
