i have had this problem for years. have discussed it here but long ago. motor starts on one pull idles all day, will run wide open for maybe 10 minutes or until i slow down then it dies and will not fire until it has cooled (15 minutes or more) does the same thing over again. temp is good. i changed the ignition coil (70$ wasted). now i am curious the oil sensor or switch might be opening when it gets hot. how do i bypass this switch to try this out? it has one wire on it. i disconnected it - no spark, then grounded it - no spark. any other suggestions welcomed. Outboard mechanics don't help because this cannot be repeated in a tub.

Sounds like a breakdown in the electronics when engine warms up. Start troubleshooting the electrical system,CDI.com should help along with an digital multimeter

I'm thinking pulser coil next. ( pick up) I found one cheap but I would like to check it first. If anyone knows how? What do I need to pull the flywheel?

It might be a bad spark plug...only costs a few bucks to find out!

An impact gun to remove fly wheel nut or 1/2" breaker bar a torque wrench to reinstall the nut

Thx guys. I'll be trying something soon. Spark plugs were checked long ago.
