i have an 05 f-60 with jet drive. ill be out all morning runing up and down the river and no problem. on my way back ill be on step and my engine starts to shutter. i found a vacum like off my fuel pump i reintalled that got a new fuel line my old one was getting realy soft. cleaned out my fuel filters and tested it out ran great on the lake took it to the river no problems that day then the next day it started again. when it happens i can hold the throttle open and with in a few minutes it gets better and were off again or if i let it idel to. i drained my tank also added new gas and isoheet. is there any way i have a fuel pump issue or what any ideas would be great
