First time out engine started and ran at full throttle for 5 minutes, sputtered once or twice than died. Wouldn't restart. when I got home I checked fuel for water and none present, even filled a glass jar and let it sit overnight, zero separation. Thinking maybe injectors since I've had that problem in the past but thought if this was the case it would start, just wouldn't run when throttled. Pulled fuel rail, full of fuel, so at this point i don't know where to look next.
