@what do your plugs look like? The engine is a honda gx25? Have you checked the valve? Done a compression test or a leak down test? It does sound like you have a lot of soot buildup inside your engine. Mist likely lots on your combustion chamber, oil sump, valvetrain etc. of course you changed your oil filter frequent etc. what‘s of greater concern is that your engine actually stops. Time to go over this engine and possibly consider a partially teardown/rebuilt.
