I have a 2006 Suzuki DF70 that shuts down before full throttle around 5000 RPM. Had it serviced by Suzuki mechanic who couldn't duplicate the problem but still did a full service and replaced water pump, put on new prop, and drained old fuel. Motor worked fine first 2 times out but started doing same thing again 3rd time. No over rev or temp lights come on, unlike the first time when it happened. Fuel shouldn't be the issue, using small tank with fresh ethanol free fuel. Once motor shuts down (not idle down, completely shuts off) it will start again after 30-60 seconds and run at idle speed. I'm going to let the mechanic have it again but any feedback is appreciated.
