I have an 885 that powers down or acts starved for fuel. I've replaced fuel filters and have plenty of fuel. While I'm mowing, and if I hit some big brush and sometimes when I don't, the tractor goes to an idle. I can press the accelerator and it won't do anything but idle. I Give it a few seconds, then it will go ahead and speed back up. I'm dis-engaging the clutch during this too. Any ideas? I'll run some injector cleaner in the fuel ans see what happens there. Any help is appreciated.
