2005 150 hp evinrude (carburated) Had problem with fuel delivery. Hooked up different hose and tank all well now. Suspect anti-siphon valve. When running, until warm runs very well. After 3-5 minutes shuts off. has fuel and spark but will not start until cool. Thanks in advance.

If getting fuel and spark it should run, try squirting a little gas in throat of carb to see if it's starving for fuel.
