Engine stalls going over speed bumps

Hmmm... I does seem to want to die almost instantly when I go slow over it. But I can drive the car all day long and hit bumps in the road and nothing happens. Maybe hitting bumps in the road is so fast that the car doesn't have time to react to any electrical disruption?

The difference would be that a bump is a bump, the speed hump is an up and down motion. It's possible something (in the harness, something grounding out) is moving just enough at that particular moment to kill the ignition.

Certainly worth a look.
