    Problem with motor need help

    I have a older Mariner 30hp mod689l 412020 which is still in very good condition.The motor starts right up and run good for about 10 minutes than cuts right off like it ran out of gas. It will start right back. Up again but will do the same thing.Any help will be deeply appreciated.

    How do I test it for losing spark? Do I need a spark plug tester?
