Well the quad is new and only has about 25 hours on it so I doubt it is a fuel filter. I have never really jumped the quad so I cant answer that either. All though in other rough terrain situations including going over downed trees I do not have a problem. It is very odd that I have only had the problem when going over the train tracks. The only other thing I can think is a low RPM lean stall, maybe a programmer will help adjust the fuel map so I does not stall under this condition. I hope to be getting the Big 3 next month so I guess I will wait and see if that helps.
