Hummingbird 899 shutting off when running in rough water

My 899 keeps losing power when running fast in rough water. Any ideas on what's wrong and/or how to fix it?

Sound like a loose power connection

Yep. Check the connector and see if it is a snug fit. If so then trace the wire back to the battery and check for a loose connection somewhere

Try "slightly" prying the pins in the power cable apart. Be very careful so you dont snap the pin, doesnt take much

I checked all connections and I slightly pried the pins apart but haven't had a chance to get back on the water yet. Thanks for the responses.
