2006 Saturn view sitting for long time went dead won't start

Morbiusbrain

I just replaced the front brakes on my 2006 Saturn Vue 2wd 6cyl and took for test drive. I got about 3 miles down the road and determined the brake piston was probably sticking. I slowed down when suddenly i heard some noise and it goes dead and won't restart. When I went back today it was still cranking/no start but seemed like a little less power as if battery was going dead. I tried jumping but had no results. I need to get this figured out. Thanks sooo much in advance for ANY help
