Same Cut Program Won't Cut

Hello. Not sure if this is MACH 4 or operator error or something else??? I am working on cutting mounting slots for my Avid CNC and I created a test cut file with a single hole that I counter bore and then drill for attaching to the frame of the CNC Router. I then replicated that hole cut over 4 spots to test the spacing layout of the attachment holes to see if they align with the frame of the machine. I used the same cutting parameters other than material thickness. On the first cut, the program and machine execute just as I had expected. On the second cut with the 4 holes, the spindle starts rotating at work coordinate 0,0 and never moves. I've tried recreating the second tool path a couple of different ways thru V Carve pro but the result continues to be the same. And if I load a different g code file the machine cuts as expected. Pretty sure I have something wrong here... but just no idea what I'm missing... Any thoughts?
