There are a few reasons why you might have to keep resetting your DIRECTV receiver. One reason could be that the receiver is not getting enough power. Check to make sure that the power cord is plugged in securely and that the outlet is working. Another reason could be that the receiver is overheating. Make sure that there is plenty of space around the receiver and that it is not covered by anything. If the problem persists, you may need to get a new receiver from DIRECTV.
