Welcome to AF!!

Since the car does this when you hit a bump check the wiring further. It sounds like there is a bad connection somewhere. The first place to check is the battery connections at the starter and the grounds. If those are good then you will need to dig further. I would check the wiring at the fuel pump as well. You may have a bad connection there that is causing intermittent fuel flow and causing it to stall if the pump isn't getting good power flow.
