You'll need top do some investigating. It could be a bad key switch, or a bad condensor in the ignition circuit or a bad coil. Or it could be an inadequate fuel supply caused by a faulty float level, partially clogged float valve,or restricted fuel supply.
To check out the ignition circuit, when the engine dies, remove the plug wire from any plug, insert a paper clip in the wire end, hold it near a good ground and with the key on, have someone engage the starter. You should have a fat, bluish spark snapping from the plug wire. if it's orangey or yellowish, that's not good. Gotta' be bluish. If it is bluish, then I'd say that your ignition MIGHT be OK. Feel the wiring right after it shuts down as well as the coil. Are they really warm or hot to the touch? If they are then you have high resistance in the wiring or your coil is overheated because your using a 6 volt coil on a 12 volt system without a ballast resistor.( A true 12 volt coil has the reistance built in to it but to use a 6 volt coil requires a resistor to drop the 12 V current to the coil by about 50 % .)
Start it up again and run it till it stops, then holding a can to catch the $2.50 a gallon gas, open the plug on the bottom of the carburetor. Fuel should gush out in a continuous stream for as long as you hold the can under it with the plug out. If you pass that test, check the vent in the gas filler cap to make sure that it's open. if you don't get a big bunch of fuel, check the "secret filter'in the fuel elbow on the carb and work your way back tot he tank to find out where the obstruction is. If you don't find anything, you'll haveto take off the carb and check the float setting and the float valve.
this ought to get you started (No pun intended!). Do everything systematically and record the results so you can recall them. Get back tot he forum so we can help you if you get stuck.
