AC Issues have me baffled

Update. We left the CG in Holland, Michigan this at 11a this morning. Pryor to turning off the pedestal 50a breaker, I reached in and started to pull out about (3) ft more of power cord from the reel. Heard the transfer switch click and lost ac power to the coach. Quit pulling on the cord and the ac kicked on at 20 seconds as it should. Me thinks that something(wire connections/brushes) in the cord reel itself might be the culprit. We are now at a cg close to Mackinac Island for 4 days or so. Plugged in with no problems. I will check the cord reel for loose connections or try and find a mobile rv tech if one is available here. I know my limitations when it comes to electricity. I remember reading a discussion on another forum(?) about cord reels causing electical issues. Now to find which forum.
