Hi, my name is***** will be assisting you.
When this is happening have you checked to see what kind of spark you are getting to the plugs? I am thinking that you have one of the two ignition coils that quit firing after it gets warm. The best way to check this is to run the machine until it starts acting up and do a spark test on both plugs. If you are not getting spark to both you have found your problem.
