Thanks for the response. I realize how simple these beds really are so while waiting for responses and ideas from other TanTalk members I decided to cut the power and inspect each individual wire lead running through each of the 4 large plugs on the back. I found 1 lead that had been getting hot and in turn it had melted the female end badly enough that it may have been the problem. It would connect sometimes and not others depending on the heat load I'm sure. I replaced both ends of the plug and it's been good for 10 running hours. Fingers crossed!!! Thanks for the ideas suncitypembroke and I have your number now suntangod.

Thanks,
