With that said, last night I ran the car pretty hard well like 2 hard pulls. After the 2nd pull the idle dipped down real real low like 200-300. Got the car home, and this morning started her up and it died. Tried 3-4 times same thing it'll start then kill itself. Checked everything nothing is loose in the bay.

I'm stumped don't know what it could be

 

Basic boltons? That is not very descriptive. What is your fuel delivery setup(i.e., pump & regulator)?

I would say start with your injectors. Take them out and see if they have gotten gunked up from the E85. I've seen quite a bit of horror stories about E85 vs injectors on here so if I were you, I would start there.
