Engine stalls going over speed bumps

I'm not sure if this is the proper thread to post in,but just as the title reads, my dart stalls when I slowly go over speed bumps. In order to keep my headers from dragging on the speed bump, I take it nice and slow over them. In doing so it causes the engine to die. Could it be that too much load trying to roll over the bump that it is dropping the rpm too low? I believe the idle is set near 750. I have a 360 with a 2k stall converter in a 727.
