user18128: I discovered something quite unusual when working with stockfish 10 chess engine in arena. The discovery leads me to ask: Why does Stockfish_10_x64 have a Node Cap when searching moves based upon amount of Nodes used? 

user13544: To play a position, an engine is usually given a search depth. Arena always does this. Probably in your case the search depth was set to a limited number of nodes. You can check this by keying in CTRL+L. The adjust level box pops in. There, you can see how the depth was specified, whether a time limit, a nodes limit, a search depth limit or an infinite depth.
