Spontaneous PC Reset

My partner and I have a rather unique problem. Our design simulates perfectly, but when we burn it onto an eprom the program counter seems to spontaniously reset itself whenever it reaches instruction 3. We're both quite baffled by this behavior, especially since we've run it through the xilinx tools twice and received the same results each time. Any suggestions would be greatly appreciated.
