Sounds like the problem is your battery is not charging when you are riding. The most common cause is a faulty regulator / rectifier. Contact a motorcycle wreckers for these parts, or your yamaha dealer.
Easy way to test is, when your bike is running, and the lights start to dim, before the bike shuts down, using a volt meter, test the voltage at the battery terminals, should be about 14V. If faulty rectifier,no charge going in to your battery, then the reading will be low, about only a few volts. If you dont have a volt meter, then any mechanic shop can do this test for you. best to have this done before buying any parts.
