I have been experiencing this problem for some time, off and on. I would like to know if anyone can give me any ideas on it before I seek service. While driving, the power to the dash gauges, radio, air and power windows suddenly shuts down. As soon as I step firmly on the brake to stop, everything comes back on. This will repeat many times, always coming back on with pressure on the brake. Then it will not happen, sometimes for months at a time. Then it suddenly starts happening again. I can hear a faint click when I apply the brake prior to the power returning. Driving me crazy. Any ideas? Thanks.

 

Did you ever find out the issue with this. I am having the exact same problem. Please email me at bigtrux80@hotmail.com with info.
