Remove fuel cap to see if there is alot of fuel spraying back into tank.I have replaced ALOT of fuel pump hoses that have split between pump and sender clamp inside of tank.Lack of fuel pressure creates a very lean condition with the injected models.

did you drain the gas before putting it away last season? If not, I would drain all of the gas and put in fresh gas, also replace any in line gas filters

Where did you get it fixed for $300. Dealer wants 6 hours labor and $400 in parts. Total cost will be $1,000.
