Looking for some help on a 5040...started acting up, like a vapor lock in beginning or air in system... Bled it and got started and then it died 30 minutes later and wouln't start...no smoke like you usually see as it fires up. Starting to think the lift pump is the problem... Any thoughts with those experienced in this model before I order pump and probably a new fuel filter while I am at it. TIA
