After reading your post many times I think you hit on the real problem and don't even know it. Why did the epoxy lining crack? If you put an epoxy lining on a solid substrate that does not move or expand there would be no reason for it to crack. Linings don't crack unless it is the result of some other action.
Your epoxy lining cracked because your block wall cracked. Why did your block wall crack? Was it done properly? Were the footings designed to support the load without any movement? What was your rebar schedule inside the block wall? I would wager you that your epoxy lining cracked because your block was not properly constructed.
Just a thought. I am not pushing one product one way or another but a product is only as good as the surface you put it on.
