coils and stator and cdi tested good but for some reason I put new plugs in and the spark gets weak after a mile or so. What causes a pug to get weak spark

Stator goes weak after they have gotton hot.Than the sled will start and test ok the next day.
will the stator take out plugs? If I put new plugs in the sled runs good then the spark gets weak under a load. I tested the stator after the sled was running for a while

coil????I don't know...just suggesting.I am not electrically inclined.That stuff will drive me insane.
Try changing the plug caps
The plug caps were tested with an ohm meter and they tested ok

replace them anyway.
Cheap thing to eliminate.
