1995 SPX bad/no spark after it's been running for 5-10 minutes.

Hello! It fires up really easy when cold, but loses spark and shuts off/starts running bad after a couple of minutes, i have changed the ignintion coil and spark plugs.

Overheating?

 

[NoelNicklasson]

I don't think losing spark has anything with overheating to do.

Yeah you’re right. I had not read his post correctly. Rectifier?

 

[JeremyD615]

That was my thought too, but the rectifier doesn’t generally cause it to shut down... You can try disconnecting the red wire going to the rectifier temporarily to see if it there is any change...

I had issues like that on my ATV and a long time ago on my mini bike. It was the stator. In what way this could apply to an old Sea-Doo?
