First off, do the following SAFELY... engine cool, well ventilated area (outside). Have a fire extinguisher handy! There should be a drain plug on the bottom of the carburetor. Remove it, and watch the gas flow into a catch bucket. There should be rapid flow at first, a half-cup, or so, as the gas in the float bowl drains out. Then, the flow will taper off to a slower flow. Slower, but a steady flow of gas that is enough to fuel the engine. If the flow is very small, or even just drips, you have an inadequate supply of gas to the carburetor. It could be a plugged filter up in the tank, the screen in the sediment bulb, or there may be a screen in the inlet fitting screwed into the carburetor. If the gas continues to flow at a reasonable, steady rate, this would point to ignition problems, possibly a bad coil. Have a spark checker ready when it "dies", and immediately check for spark, to verify if lost spark is the problem.
