Just bought a 2003 mobius dd 310 efi with 197hrs on it in sept of 2013. Had it winterize and the water seperator and fuel filter changed. Got a fill up and put it in the water 2 wks ago - did a couple laps with no running or starting issues whatsoever. Loaded up the fam for a cruise/tubing session yesterday and it started stalling out to the point that it wont start now. Hoping this is a simple fix... any ideas? Sounds like it may be starving for gas, but not really sure.
