Van intermittently stalling

What is your question?

I have a 2012 town and country that has been intermittently stalling after about 2 hours of driving. I use the vehicle for work and it's a lot of idling and stopping and going. I have had the van for about 3 months and it ran perfect for the 1st month. Now when I drive the van, about 2 hours into using it the van will stalls. When I turn the key all the electrical will work but no crank. I have to wait about 30 minutes then it will start up like nothing happened. Sometimes I can get it to start after 5 or 10 minutes but sure enough it stalls a few minutes later. Then I have to wait for 30 minutes for it start. It also shows no codes. I've had the battery, alternator, TIPM, thermostat and CAM shaft sensor replaced but still the problem persist. It's been to 3 different mechanics including the Chrysler dealership 4 different times and no one can tell me exactly what it is.

How long has your 2012 Chrysler Town & Country had this problem?

2 months
