Sounds like the choke control isn't kicking the choke off properly. Then it floods. Just google for (your Honda model -automatic choke control).

There's a video on replacing the control.

I would also check the gas cap to make sure it is clean as a plugged vent will shut off fuel flow, like putting your finger over the end of a straw, and if not that check to see if you have spark when it stops as that could indicate a coil going out.

First put a new spark plug in. Then if it continues, proceed to further diagnostics. This has been a common problem on these hondas with NGK plugs.

The thermowax is a common problem on these too, but usually that causes it to not want to start to begin with. Is the choke closed when it shuts off? To check the gas cap, loosen it and see if the problem goes away. If so, replace the cap. If not, that's not the problem.

very many thanks, noted your comments as to thermowax, no it starts on first pull so i assume thermowax is not the issue !! as to chowk closed when it shuts off, let me observe this ( i assume i should remove the air filter and watch ? or any other way to do it ?? ) as to gas cap, noted , i will do that tomorrow and advise, best wishes

A float issue can also cause this issue.
Once the fuels burned out of the bowl it shuts off, left to sit a small amount of fuels leaking into the bowl and it starts again.

Yes that's the way to check it. It should be closed for starting, then open for running.

This is the thermowax Cheese is referring to. It heats up and opens the choke for running. His comments indicate, however, the problem is likely something else.

Happy holidays to you all ! just now i have started the lawn mover ( after removal of air filter ) and watched - butterfly remained opened all times - ran for about 3-5 minutes and shut down - then i had removed the assembly to see choke actuator - piston was sticking out ( tried to push it back gently but did not move ) - again / it started on first pull - ran for about 3-5 minutes and then shuts off ( does not restart )

Sounds like a fuel problem then. Something is likely restricting flow of fuel into the carb bowl.

before i have started, butterfly was closed, when i have started, it opened up ( does not close ) and remained on for about 4-5 minutes i see gas flowing the carburetor bowl also, is this choke actuator ( piston ) supposed to close ? also one of the bolt ( out of two ) is now sleeps / any suggestion ?

The choke is supposed to be closed when the engine is cool, then open when it starts up and stay open when the engine is warm. How fast is the fuel flowing into the bowl area? It needs to be a pretty steady flow, not a tiny dribble.

When it was running? You mean when the mower was running or when the gas was running? You can't see the flow of gas while the mower is running, but 5 minutes seems like a long time to just let gas run out. Please clarify.
