Radio, windows and interior lights quit working at times on Ford F250 diesel while driving?

While my husband is driving his Ford F250 diesel all of a sudden his radio will stop working, he can't roll the automatic windows down, and the interior lights will not work but the eject button will still work. He is very frustrated because his air conditioning also is not working. When he drives for awhile the radio, etc will suddenly start working again. What could be causing this? Thank you!Radio, windows and interior lights quit working at times on Ford F250 diesel while driving?i have no idea!
