First thing to do is check the fuel pump pressure. It should be 56 to 63 lbs.

Yeah I'm thinking fuel pump too, what could have happened is when you went over those bumps you really stirred up the fuel in the tank and the pump picked up some crud off the bottom and it would take just about that long of travel for it to mess up,the pump, the pickup screen and filters.
