I have a Ryobi pressure washer with a Honda motor. A GVC190. After it runs for about five minutes and it shuts off so I took the car apart, cleaned it cleaned out the fuel tank and cleaned the fuel lines and I also cleaned thegas tank cap to make sure it was venting properly

Wouldn't hurt to replace the spark plug. Spark plugs will do weird things. I have personally seen this exact issue with Honda engines where the spark plug hot fail, and then start working after a few minutes and then fail about 5 minutes later.
And it would be nice if you could go back to your other 2 post on this subject and hit the delete button at the bottom of your post. Multiple post just causes confusion and is frowned on by the techs on here.
