You should really run the software update, as it does add some features and faster boot times for the 788. After that, test the voltage that is going from the boat to the plug in at the unit. Make sure that it is at least 11V. Check for corroded connections at the fuse block and on the back of the unit. With it powering down at random times, it really does sound like it is losing voltage due to a failing connection.

You can register the 788 here and get the software it needs.
