"Every once in a while, when I
"Every once in a while, when I start my 5.0 litre yamaha, it will run for a minute and then stall. There is no fuel in the carb and pumping the throttle does not prime the carb. If I pour gas into the carb, it runs for 10 seconds and dies again. It typically will not start the rest of that day and will start and work fine the next day. I know it is not getting fuel but cannot figure out why the fuel does not flow for one day and then will work fine the next. I don't think it is vapor locked as the engine is cold when this happens. It has never happened when the engine is warm and otherwise, the engine runs great. Any suggestions as to what to troubleshoot would be appreciated."
