Stuck in the trees

[redrockfarm]

Huge job of cleaning up after a straight line wind storm. My LS170 has always been my go to labor saver since 1999, but this time it suddenly went dead as I was idling and waiting to move the next tree that was being taken down. The power all of a sudden went dead, checked battery it shows 100%, replaced key switch lights came on as I sat in the seat, turned the key on and all went dead again. I did have a blown 5A fuse which I replaced but that had no effect either.
Also I am unsure as to how to release the hydraulic pressure to raise the boom arms with no power.
Any suggestions from someone who has experienced this is appreciated.
