Howdy CB,
In my case i've had that happen and it was due to a weak starting (aka auxillary) battery--the 12V lead acid.
The other issue of which i've heard is the subject of the recall of the motor control unit (MCU), namely a degradation of the insulation within the unit. Considering your humid and salty environment it may be that corrosion or deposits may be causing a similar effect.
