Run your ground and power directly to the battery and you will probably solve your issue. My 162 and my depth sounder did the same thing until I ran common wires for them and a couple of other things. Get them off your ignition circuit if that's where it's drawing power.

You would be suprised how your 12 volt battery fluctuates with the loads drawn from it. Unstable voltage regulators ,crummy wires, connections and too small a wire feeding the unit., Oh yes and your voltmeter gauge on the dash will only show long term dips in power like 1/2 second and longer. Your Garmin can see a power dip of say 10 volts for 250 milli seconds and off she goes. Perfectly normal,nothing wrong with unit. Your biggest culprit is your trim pump.It draws a good bit of amps which can dip a battery not fully charged.Take a volt meter and measure your battery at rest. 12.75 =full charge 12.50=3/4 charge 12.25 1/2 empty or full your choice. While running at 1500 rpms or more you should see at least 13.25 volts min.
