communication cable

Since I replaced my Pentair Intelliflo pump, the communication will cease between the pump and my easy touch panel. They will talk and work fine together for a few days and then all communication stops. After I cut the power to both the panel and pump, let sit for about 5 minutes and turn back...

Both my communication cable for the pentair superflo vs and the aquacal temperature cable have been cut. That is why it hasn't been working. Is this something that I can fix myself? How do I figure out what cables to order? Any help would be greatly appreciated
