Sounds like an issue with the common wire(s) because it affects all zones. The common wire is the link to all.
Because it worked for a period of time, then stopped, it could be a dreaded intermittent (loose connection).
I suggest you go to the valves unbundle the common wires then run a wire from the common connection at the Rachio main box to a single valve, then try a quick run on the valve you selected.
