When I left Best Buy on 54 an hour ago it came back on. Also I found ANOTHER tower that's on today, I'm a quarter mile west of Parsons on MLK in Seffner insisde a store with a fairly strong 4G signal. Not sure what tower it is yet, there is one on Kingsway and MLK that has had NV pannels for a while, that might be it. I will map later when I have time.
