ok boat runs fine till i stop to swim or somthing. it then starts and i can idle out, the longest i have idled out was bout four to five min. was in no wake zone. then punch it and it runs out of gas. the fuel filter is half out of gas, starved. so far i have replaced fuel pump, anti-syphone valve,fuel line, fuel filter, fuel pump relay, checked fuel tank vent, drained tank vacuumed out what little debre was in it, refilled it wit pure gas no ethanol.and still does it. the only thing left is ground, and alt. it pulls power from alt. when boat is running. do you guys have any thoughts bout the subject?
