It could be a dirty egr valve. There are many posts on how to check it. Just do a search for it.

What are the circumstances when this occurs? Are you driving by a Krispy Kreme with the 'Hot Donuts Now' light on? A gun shop? Cabelas? Camping World?

My truck abruptly cuts out too. I think its a steering/throttle interconnect problem.

Seriously though, check egr valve. If that's not it, I'd take a look at the turbo vanes.

It could be a chaffed wire, while the truck is idling move the injector harness from the Ficm to the valve covers back and forth and see if you can duplicate the engine cutout.
