Trouble starting GMC Sonoma

lapwing1

while having trouble starting my Sonoma and after turning engine over repeatedly, all power cut out, dash lights, all power, power came back after a few minutes but when I tried to engage starter, I heard a loud click from under the hood and all power cut out, this happened several time and now no power at all, battery is good and have power to fuse box, could it be a fuse?

What year is your truck? Which engine?

How do you know the battery is good?
