I have a Humminbird 898 with di/si and the other day on the lake it was shutting off on its own I would turn it back on and 5 minutes later it would shut off. When I got home I checked the voltage and it had power. ( I don't think it was over heating because it was a great 70 degrees and it didn't feel hot). Has any one ran into a similar problem any help is appreciated thx.
