Reporting back on this. My son called and told me the gauge went to zero. I have my fluke hooked to the pump power wire along with a LED to make it easy. He said it was reading battery voltage the whole time and the light was on. The pump is still in warranty till October so I'm going to call them tomorrow. It has to be the pump. Why cycling the key seems to fix for a while I don't know but not going to over think it.
