I don't think it is a wiring problem with your thruster. If anything, inadequate wiring will reduce the current flow. Your electronics are shutting down because the voltage at the battery is getting too low because there is too much current demand, not too little. I am back to my original suggestion -- your batteries are weak, either under charged (verify that they are reaching full charge and that you have this problem when fully charged) or worn out (ie, significantly impaired capacity). You can confirm battery capacity with a load test. If they are proven bad, and if you have the facility, try equalizing them. Otherwise, I bet everything will be back to normal as soon as you replace the batteries. For what it is worth, lots of boats don't have a separate bow bank for the thruster and work just fine.
