Answers :

Check the bottom of the gas tank for dirt/debris and the float bowl for the same, if it has a fuel filter check that also. Sometimes, if there is debris in any of these places it will settle down when the gas flow is stopped. Then, depending on how the machine is being used or moved around while it is running, the debris will slowly be pulled into the gas flow until it creats a blockage and starves the motor of fuel. When the motor dies the debris settles back down in the tank/float bowl and the motor will start again. Clean out anything in the tank and float bowl and replace the fuel filter if it has one.
It's the gas cap. It won't vent air in the tank so the carb is starving for fuel. get a new cap or crack it open enough to let some air in while your running it and I should run fine.
