I'm pretty sure this is somthing different. I had to replace my p/u twice. Once the car wouldn't start...the other time it started to die while driving but I would have to restart it. It wouldn't restart on its own. I also remember putting a different distributor on the car too.

When it shuts off, it is only for a split second and starts right up again on its own. If that happens to you on a stick car...it'll scare the crap out of you it jerks so hard.
