This sometimes happens with other radios if you transmit into a high SWR. It has happened to me when I accidentally key the radio without connecting an antenna. The transmitter's foldback circuitry will appear to briefly shutdown the radio to protect the finals. Check the antenna to make sure the coax is good at both ends or try a different antenna or dummy load.
