Check for a blown alternator fuse.

alternator fuse appears to be fine

So once vehicle cools off vehicle will start ?

or does it need to be jumped?

if the batt has enough juice, yup.. I've been carrying a backup batt to swap out when first one tanks lol. it's like the heat makes something expand and stop allowing alt to flow charge to batt

Do you have an extra fuse that you can replace the alternator fuse with just to rule out that the fuse is good ? You can also use a test light to make sure fuse is good.

not as of yet but I'll grab one and check that as well as all connections when I can crawl under it. thanks for the suggestions, hope to attack this this weekend.
