Unexplained stalls after big bump

Hello Folks,
Has anyone experienced an issue when the car stalls after hitting a large bump in road. I have had this happen about 6 times in the last year. The dealer can not see anything wrong. I thought it may be the fuses that jiggle loose. I tightened them and still had the issue happen about two weeks later. This one seams like a real safety issue as I have to put the car in Nuetral and then re-start the car. I had this happen once on the freeway and luckily I was in the right lane and was able to coast to shoulder lane.

This also happened to me last winter. I had a bad bump on the road to work. I think it may have something to do with the fuel pump safety. The jolt trips the switch and you must turn off ignition to reset the switch.
