Rebuilt top end on honda 350 rancher two times but rings keep going out after 2 good rides?

Cylinder bore and hone on stock was done professionally. It is a aluminum cylinder with steel sleeve. Rings, piston and wrist pin were replaced with Wiseco's replacement parts specifically for this 4 wheeler. Piston rings were staggered exactly to Wiseco's instructions. All gaskets were replaced and valve seals were replaced. Ring gaps were checked and in spec. Air filter is pretty clean and attached. The 4 wheeler runs excellent for the first 40-50 miles then slowly goes to **** the next 10-15 miles till it smokes up a storm. When engine is disassembled the cylinder hone is wiped smooth and ring gap has slightly increased valve seals and all gaskets still seem to be in good shape. I constantly check oil and oil stays clean till blow by and cylinder wear occurs. I have installed rings on personal cars dirt bikes and Pwc's before without issues but this 4 wheeler is throwing me through the ringer and making me feel like an idiot.
