Check the terminals on the wire ends. I have to clean mine every year. A poor connection at those terminals will cause that or a section to just shut off for a bit then turn back on. I replaced the coils on mine back about 6 years ago. The old Century 500 gal sprayer sits outside all year and they are still going strong.
