I have a 2013 Yamaha 115, low low hours. Confession....it sat for a while for personal reasons. Anyhow, get her back running through a mechanic. It needed a VST (replaced new), cleaned the injectors, replaced filters, fuel pump works. Put in a new fuel tank and hoses etc. (tested good). It starts and idles but when running under load it dies in about 11 minutes (almost consistently at 11 minutes). Stays primed, and will usually start again but doesn't run for any length of time. Tried fuel from a stand alone tank to eliminate the new tank with no change.
Attached clear tubes and gauges to fuel pump and VST. Started and watched the VST gauge drop pressure after about 10 minutes - the fuel simply quit coming out. Waited a few and she restarted, etc. Never loses prime and the VST doesn't empty; it just stops pumping.
Using REC90 fuel. Mechanic and Yamaha support is at a loss.
Thoughts?
Thanks!!!
