The air filter is under the seat. The Maxim should be air cooled so they tend to produce a lot of heat. However, you would know if it is running hotter than normal. A slight blockage of one of passages could cause you to run lean which will make it run hot.
You could be running hot enough that it is causing one or both of the coils to fail. Then when it cools down the coil will fire again.
