This sounds more like a lean fuel condition than ignition. If it was stored over the winter without the gas being drained or a fuel stabilizer being added, you'll likely have varnish build-up in the fuel system that is not allowing sufficient fuel flow. If your engine is fuel injected, it's likely your injector is partially clogged. If it's carbureted, your carb jets may be partially clogged or your carb float may be sticking and not allowing the needle valve to fully open. Fill the gas tank with fresh gasoline, but leave enough room for a can of Sea Foam. The Sea Foam may be able to break up the deposits and allow fuel to flow again. However, there's no guarantee and the fuel system may have to be disassembled to be cleaned.

ALWAYS have a fire extinguisher on hand when working on carburetors. Drain the carburetor. There should be a plug on the bottom of the carb float bowl. Remove the plug then replace it after the fuel drains. Remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the air screw on the outside throat of the carb and spray into the screw hole as well. Be sure to put the air screw back in. IMPORTANT > do not tighten this adjuster down. Only screw it in until it LIGHTLY seats. Now turn the air screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine.
Can I get a “very helpful” rating on this answer?

when the engine dies pull out the spark plug and earth the plug on the metal part and turn it over dont hold the spark plug as you will get a shock if the plug sparks you know the ignition system is working.if you have no spark do a compresion test to see if there is a problem with the engine.if that ok you will have a fuel problem make sure the breather on the fuel tank isn blocked or trapped.

where the valves set cold or hot? could make the world of a difference...is there intake leaks? bad floats perhaps....its a problem that will take some time cancelling out problem by problem
