I have a 2004 Hdpi.. recently when I reach 50 mph it cuts out, or when i idle for a while. Anything below 50 it runs fine. I’ve changed the vst filter, the strainer filter, and the canister filter. Only ones I haven’t changed are the mystery filters In my HP pump.. all compression checks out, only has 15 hours on it after the rebuild. Anybody have any suggestions?
