BR starts, runs perfectly cold for not quite 4 seconds, dies, restart keeps running till warm, runs all day no issue, if I blip the throttle before it dies it stays running. I replaced the Starting Enrichment (SE) Valve, cold start device on the Carb, electronic choke. I traced back the leads in the electrical diagram to the ECM. I check for 10 K-Ohm resistance of SE valve, energize per manual for 5 minutes, left terminal (+) right terminal (-), apply vinyl hose to enrichment circuit of carb, blow, if no air flow - OK. If resistance checks out, air flow before energizing, no air after 5 minute energizing (SE) should be ok. Could be loss of power from Electronic Control Module $224 ouch.
Otherwise BR performs perfectly, just got to start it twice for now and it's fine all day. Could be ECM timer for EC is kicking in to early to shut down the cold start circuit prematurely.
