I recently had a problem with my first gen is300 where after the engine gets all warmed up it shuts off after 10-15 minutes I came to this conclusion after the first time it happened where I figured it was the spark plugs,coils and wires so I changed them out and I’m having the same problem i also checked the MAF sensor and it had very little debris so I cleaned it made sure not to break the connectors. I also noticed someone had said that it was a loose cam sensor and when I checked mine it was fine so I’m stumped I’ve noticed you guys on here are very knowledgeable on this car and your help would be greatly appreciated

The engine shuts off or you loose all power to everything?

The engine is shutting off. After it shuts off I’ll turn it over and it will turn on and immediately shut off again. If I let the car cool down for 5-10 minutes it runs smooth until the engine heats back up and does the same thing again
