Answer
Hello Jr:

Check the Gas Tank Cap and Ensure it is Venting the Tank Properly. A Bad Cap Creates a Vacuum in the Tank and the Gas Cannot Free Flow to the Fuel Pump. Check for Fire at the Plug/Plugs when this Happens. A Bad Coil will Cause this. A Bad Shut Off Solenoid in the Carburetor Bowl (if the engine has one)will Cause this Problem Also. Send me the Model and Type Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

Good Luck
