I got 2008 6.7 an having some majors problems with my truck shutting off driving down the road. when it shuts down the check gauges light comes on an the light with the gas pump an water droplets by it. when it dies it also throws a code P2509. i changed my batteries an now when it dies it dont throw that code anymore. Now on my edge cts its throwing P242B and P2453 an still cuts off driving down the road. Sometimes it takes 5-10 min to let me crank it back up if i was running the truck hard.

 

I can't help you much but here are the codes you are getting. It's like you have some loose wires or water in the fuel filter.
