Got battery power to all accesories, but when I turn the key I get nothing. No crank. No click.

It used to crank a few times then start up.

Sound like ignition? starter?

 

I would say, test your starter.
Check for loose wires.
Also make sure that your battery terminals are nice and tight.
I have found that if the terminals are loose when you try to crank it the surge severs the connection and you get nothing at all.
I have had this problem in the past and all I had to do was tighten them up.
