Hi,
If the starter isn't engaging and basically you lose power to most everything, the first thing I would check is the battery terminals. If there is a bad connection due to corrosion or a weak terminal, this can happen.
Take a look through this link. It explains how to check/repair this type the issue.

Let me know what you find or if you have other questions.
Take care and God Bless,
Joe
