Sprinkler clogged with debris from well. This solved the problem. You'll need to clean the trap regularly depending on how much it's trapping, or the pressure will drop behind it when it's clogged. I installed a small solenoid that periodically drains the trap and it works great. No more clogged sprinklers.
