Will start then stop after 5 min not the carby maybe the electrics?

Your crank bearings are failing. as the engine heats up the gap opens to the alternator and pick-off and the spark fails.
I put in a new crank last winter unknowing the crank was dropped by UPS (I should have checked it) as the bearings wore out over the first month of use the time to fail would be shorter and shorter until it wouldn't run at all. All the time troubleshooting the electrics and replacing all components. Replaced with a warrentied crank / bearings and seals and all is well. I would replace the coil first though, it's cheap and could contribute the same symptoms.

To begin i will say that it is more the way you proceeds that make you solve the problem...and also good analyzed...
check easiest and closest thing for first

1. check vent tube and gaz cap (make sure it let air into the gaz tank)...if not you are running out of gaz in about 5 minutes i will say
2. get the gaz tank ready to remove fast...so when the engine stop you can check out fast with you're spark plug for missfiring...sometimes a bad stator loss continuity when getting hot
3. honda as a problem of intake valve getting tight....if intake clearance is zero then put new intake oem valves cause ajusting the valve with the old valve will solve the problem for a short period of time...(the titanium valve as a molycoat onto it that when remove....make valve without protection and getting tight all the time)
4. if after all those test you are not gettinf no where i will give you my msn and then we shall make that thing running
