Hope this helps someone else.
Spent the wknd in Florida's east coast and had a great time, until.
Last of five dive wknd and this happened as I was getting back into the boat on the ladder.
Single Tank Adapter separated from back-plate and tank also had 4.00 lbs extra weight in pockets. I run a long hose setup and had clipped off the primary to my d-Ring and use my snorkel to swim/wait for the boat.
As I climbed up the ladder, the tank separated from the back plate and fell back into the water, which pulled me back into the water. Entire system was separating and the tank was going down/floating away and dragging me via the short hose (bungee'd to my neck).
Got the short hose off my neck (lost snorkel and mask in process) and grabbed the attached long hose primary back in my mouth. I got back to the boat (After dropping weights) and with the help of others got all the pieces back on the boat including the tank.
Back-plate, harness still attached to me, single tank adapter and tank cam bands attached to the tank and my wing floating around in the water like a life vest.
Come to find out both single tank adapter bolts were gone and no signs of stress on the back-plate.
Ok, I see and have experienced a point(s) of failure with a single tank adapter.
1) Two stainless steel bolts with wing nuts (how they failed is beyond me this was dive 30 on this setup)
2) All the load was on the two bolts. Failure was the tank separated from the back-plate.
I'm going to research a way to route the cam-bands through the back-plate and use the adapter (instead of through the single tank adapter) and have the adapter also attach to the back-plate.
This will put all the weight of the tank on the back-plate + cam-bands and not on two bolts.
