90 35th not starting

I have a 35th auto SC 74000 totally stock yesterday while driving it stumbled and shut down, stopped and it fired back up but kinda rough made it home shut off. Tried to start it, nothing. Waited hour it fired up, so I turned it off and tried again nothing. Waited hour it fired, I unplugged cam sensor and tried it nothing. I was thinking crank sensor??? If anyone has ideas I'd appreciate it thanks

could be the dis, my 91 was doing the same thing, changed it out now its good.

I had a cam sensor that did similar things.

Codes were 212-214
