Hi all!

Having a problem with my 981/2 24v. When pulling my 5th wheel it starts cutting out under a load especially in 3rd. It will do it with out the trailer hooked up, but it must be uphill and really getting after it. I have no codes, everything Banks Power has to offer, and I hooked up a fuel pressure gauge. At an idle I get 10psi and under heavy load it will drop to 5. It usually stays around 8 or 9 with out much of my foot in the throttle. When it is cutting out I see the pressure bounce but it never bounces more than about 1/2psi at a time. I replaced the filter and it didn't affect anything.

Thanks,

Bill
