This could be a couple things. However, here is a guide that will get us started:

The fact that this does this only on rough roads, we have to assume there could be a wiring issue. So we need to start with checking the ground for the PCM G108. It is on the radiator support. I would remove it, clean the support and the wire and reconnect it. This should be an eyelet ring with a bolt through it.

Let's start with this and then retest it and see if it still shuts off.
