I have a 2008 ford f450 and i was towing my 28 foot enclosed race trailer on saturday. i was driving back from the track and the reduced eninge power light and wrench started flashing on the display and the 28 foot enclosed trailer felt 20 times heavier ha. Pulled over shut the truck off for approx a minute started it back up and everying thing was back to normal. Everything was fine on the stock gauges (no aftermarket yet). Anyone else ever expirence this or can tell me what happened?
