Engine stalls going over speed bumps

It is a Holley 750 and the rear end gear is 3:23. Those are very good suggestions. I had to go over two speed bumps yesterday and it died on both. That was the first it had ever done that. In the past it seemed like it wanted to try and do something like die, but it never did. Once I got it to my garage I parked it.. I'll have to go out and check on those suggestions. Thanks for any thing !
