My area was riddled with that for months, turns out Sprint was upgrading the towers for circuit switch fall back. A good way to see if this is the case put your M8 in LTE only mode (dial *#*#4636#*#*) and select LTE only. If your connection comes up with LTE then that is the case. I would also try and update your profile and update the PRL sometimes that helps with connection issues.
