I would under stand that if it happens when its is humid out.

 

You need to check if the starter is getting power during the times it wont start. Youre probably going to have to check the entire ignition system with a meter. If you can jump the starter then at least you know its something behind that. It sounds like something is "iffy" when there is a temp change. Maybe the tumbler? Maybe accessory power? Maybe a relay doesnt like temp change?

 

See that is what I was thinking the key bc I am able to jump starter. when It will not start with the key and it will fore up evey time. By jumping tbe starter.
