Just had a baby ball die on me out of no where?! I had him in a cserpents rack with several other snakes who are all healthy as can be!

I got him on the 8th of this month. He was deep in shed so I let him get settled in. No attempt at feeding on the 10th. The 17th many of my snakes were in shed and he was just finishing up. Offered but meal not taken. Last Friday (10/24) after a perfect one piece shed, he again refused to eat. Now I'm like ok wth?
He has been drinking and he defecated the first week I got him. I noticed last week he seemed to have his neck in an abnormal and very obscure position. I took him out and he was fine. It was only 2 times I noticed. Came home from work today and Boom. He dead.
ambient temp 88 inside tub hot spot 91. Humidity is 55

I am really surprised that after this short a time. he croaked out on me?
I've isolated all my snakes atm and I am scrubbing everything like it is no ones business. Anyone have anything happen like this??
