OK, most likely the limit switch cable. The problem goes away when the print head is mid range y-axis that relieves the bend in the x-axis cables. I ordered a couple new ones but at least I can still print if I start out with the print head mid range y-axis. If it is towards the front of the cabinet in y-axis I get the problem and it basically locks up when it tests the right x-axis limit. Parts are cheap, and it doesn't look like too much trouble to replace. Hope that is the issue.
