ok motor cuts out over and over again. when it is cold it does ok for about 5 minutes then it will keep cutting out over and over. I put a timing light on it it seems to stop firing then start back. Runs good for 2 seconds then cuts out then runs over and over. I am think about replacing the coil but not sure that is it.....fuel pump all fuel lines are new. I took a smaller gas tank to the lake and used it elevated above the motor and pumped the bulb but it did not affect the problem. After I ran it for 15 minutes it would barley go above idle......Thanks in advance for any help.
