Loss of power on interstate

[saznunes]

I have an 04 2500hd duramax with the Edge Attitude controller. At five diferent times I have lost power. I can put the truck in neutral it resarts immediately and i can continue on. Every time the truck was at a differnet speed.
1. 35 mph coasting
2. Towing trailer and accelerating to pass slower vehicle
3. 50 mph exiting freeway braking
4. Towing trailer and accelerating up a hill
5. 15 mph idle coasting in traffic
This has happend over the past 9 months or so. Does anyone have any ideas on what could cause the sudden loos of power.

What engine do you have? LB7? LLY? :confused:

This is important before we go any farther. :)

Have you tried without the Edge connected? That's the first thing that I'd eliminate and unfortunately the likely culprit.
