Was the previous receiver doing the same thing? Did Dish just send you a replacement receiver or did a tech come out? Random rebooting is not normal. Where is the receiver located? Excessive operating temperature can cause problems. Not as likely is an electrical problem or grounding issue.
Do you have a ground block installed? It would be between the Dish and the rcvr location, typically at your meter box, breaker box, water pipe in the basement, copper braid....if so, go unhook the ground. Sometimes that can cause exactly what you are claiming. Why it didnt do that on the old rcvr is weird, but that may have also been your tv2 issue. Its worth trying (and easy to do)
