Electronics trouble

New battery.

New battery or lack of good charge in existing battery. Should be around 13.5 volts full charge.

You probably need a new battery unless you're running your electronics and pumps from a deep cycle battery. In that case and by design, both the amps and voltage would be dropping as the deep cycle is being discharged. Cranking batteries on the other hand would lose amps but only a minimal amount of voltage while being discharged if the battery is in good working order.

How do you have the electronics wired? It sounds like to me that you have them wired into a fuse box. If so undue this and run them each independently to you battery. Make sure that you put an inline fuse on each one. I had this problem when I wired mine into the fuse box on my boat.
