1998 Powder Special will start and idle but when giving it the throttle, it dies. This only happens after letting it idle or low speeds for a while. After sitting for 20 minutes or so it will start back up. Any suggestions?
Have replaced the stator and tried disconnecting the TSS plug (this makes no difference). As long as the sled is run at wide open throttle is runs good.

What are your stator ohms? Is the TSS unplugged? What is your compression? Have you checked the reeds? What are your trigger ohms?

Compression is good. I just rebuilt the engine. I will look at the reeds this week and let you know. I dont know what you mean by trigger OHM's. But i can check this if you could tell me how to do it. I will take the sled out this weekend and run it and when it dies I will check the stator OHM's while it is dead. Thanks for your help. I will keep you posted.

Trigger ohm testing. Very quick and easy. Your ohms are supposed to be about 90. Also measure them again after it is warm just like your stator:
