LOSS OF POWER??

[glennshd]

Ok, here's the story. After pulling my 10k lb 5th wheel for two hours I had a sudden loss of power. Could not get above 30 mph. Felt as if the engine had a noose around it. I had to pull over and shut it down for a minute, restart and it was ok, service engine lite went out. I have a 2002 duramax with a hypertech chip installed. Have any ideas on a cause??

What codes did it set?

it doesn't appear to be storing a code.

Had the same thing happen to me while traveling through New Mexico last spring. At that time there was a series of posts talking about that same situation. I do not believe anyone came up with a reason. Just another mystery in owning a Dura Max/Allison.
