New to the forum here, I have a 2015 900s with around 500 miles on it. Went riding a week or so ago and it developed a nearly complete loss of power going up a hill, tank was full of fuel, no overheating, machine will still run fine on flat ground and seems to have no loss of power if left in 4wd going up hills. The machine has new spark plugs, new air filter, oil recently changed. Dealer recommended looking at the fuel pump, replaced the pump and no change, spark arrestor was also just cleaned, machine has no codes at all either. Any help would be appreciated and thank you in advance.
