6.0L Electronic Throttle Control issue

[MBahrEco12]

Bought a 06 f250 6.0L a week ago. While coming back from a ATV trip on the interstate I was going about 75mph up a hill. The truck went to down shift and when it did. The Electronic Throttle Control light came on and I lost a ton of power because the truck went into "limp Home mode." I pulled over and shut it off. Turned back on and everything was normal and the truck ran fine till it went to down shift again on a hill and the same thing happened. I babied it back home. Now the truck runs with no problems except that it is very sluggish off the line.

Any ideas what this could be or how to fix it. I've had the truck a week and it only has 85k on it. HELP!!

I have the same issue but my light comes on after pulling my trailer about 20 miles. It does not seem to lose power though. Have you gotten any help with this issue?

if you have a chip unplug it. could be bad or just loose connection.Had same thing on my truck. I just unplugged chip and plugged it back in no problems since
