I would ask the dealer to scan the computer module for any updates. It may not solve the problem but it shouldn't do any harm. Good luck.

UPDATE: This has happened 4 times now. This last time I limped it in to the dealer while it was happening and they connected a computer to it. The computer showed the #1 cylinder was missing continuously. They tried to trace down the problem but couldn't figure it out. Then they turned it off for a bit and restarted it. Whallah! Everything worked fine. Now it cannot be reproduced in order to trace the problem.
 
This problem seems to happen only after the vehicle is warmed up and driven for an hour or so. Then it happens after the vehicle is put under a load (like passing) and will continue to misfire until the vehicle is turned off and then restarted.
 
Cars at the dealer now and I have a loaner. Dealer is talking with Chrysler but they have yet been unable to pinpoint the problem. They plan to tear into the intake manifold today to check for stuck sticking sensor/valves..?
 
I am getting frustrated that it's brand new and I am having the same strange problem. I hope they get it figured out.

I just got the van back today. They have replaced the crank sensor. They are not 100% sure whether this has fixed the problem. I have some driving to do the next couple of days so I will update this thread as to my findings.

Have a 2009 4.0 Grand Caravan, the van has 4000 miles. We have had this problem since it was purchased, the engine dies when the temperature reaches the 1/4 on the temp gauge. To restart when driving, the engine needs to be in neutral and started once or twice and then it is OK, this only happens when the van sits overnight. Taking back to the dealer today, they could not find any problems up to now, they are keeping the van untill it is fixed. It is not safe to drive when you loose the power steering and turning a corner. Thanks bob

Van has been acting up all week, doing the same thing.
 
The crankshaft sensor was replaced last time by suggestion of Chrysler Corp.
 
Since I have been driving it, I have learned how to reproduce the error:
 
1) Drive the vehicle until warm.
2) Drive 65
3) Stomp on the gas as if to pass (vehicle will downshift from 6th to 4th)
4) Keep the pedal to the floor until the rpm's reach 5200
 
Then the problem appears right at about 5200 rpm. The vehicle (engine) hesitates/jerks at 5200 rpm and the engine light comes on. Then the vehicle will misfire on cylinder #1 (even under slow/normal driving) until the key is reset (turned off, then back on). If traveling down the highway, you can shift to neutral (DISCLAIMER: this is dangerous!!), turn the key off, then back on, then shift back to drive and this is sufficient to reset the engine so that it will fire again on all cylinders. Like rebooting the computer fixes it....??
 
I dropped it off again at the dealer today for service on Friday. The service person at the dealership says they now have three Chrysler's that are all doing this same thing and they have not figured out a remedy. Sounds like my van may be the guinea pig this week. They tell me Chrysler has not been able to provide any insight as to what's occurring. Once again, they tell me that they are going to tear into the manifold and start replacing parts.
 
Does anyone know what the Lemon Laws for Kansas are? I have already had this in the dealership 4 times for this problem and no resolution is in sight. It currently has about 6500 miles on it. I've had it for under three months.

What is the red line for your engine? 5200 is probably getting up there... maybe it is activating a rev limiter that is faulty?
 
6500 miles; that would just be infuriating.

That's definitely not it, then. I bet this is vacuum/emissions related, but I really don't know how to pinpoint it. Will it happen when just the engine is revved to 5200, or only under the load conditions you described above? I would think a shop would have diagnostic devices they could hook up to the vacuum system to see if it is behaving as it should.
