Starts up great. Runs for 5 mins, then Boggs down the throttle until it almost shuts off, then I engage choke to keep engine alive and sputter , so I can get it parked.
Starts great every time! As soon as it gets warm, it bogs down to 0rpm, and dies.
What is this? Something with gas/carb I’m not sure

Running out of fuel.... try running with the gas cap loose and see what happens, sometimes if the tank cant vent, the flow will stop, May also be water/contaminated fuel.
Model of the Engine will be helpful

Yup but it sounds like it restarts fine. Which restarting a warm engine shouldn't take a lot of fuel. Crank the revs up and she gets thirsty.

Definitely a fuel delivery issue. OK, perform the gas cap trick . Pull the fuel line off at the carb and check for proper flow. Fuel pump or gravity fed fuel tank? Dirty carb and air filter? Valve CLEARANCE needs checked.Here it comes, did you replace the spark plug yet? That should be number 1 on the list.
