Had no spark on one cylinder, replaced coil and ran fine for about 30 minutes, started right up next day and ran for about 10 minutes and died like you shut it off. Replaced power pack still no spark on both cylinders. Any suggestions please?

Thank you for the reply. I have done that, disconnected kill wire no spark, checked stator resistance it says zero on meter spec is 500 ohms, checked output dva of stator had 145 spec is 150. Next is timer basa resistance from black/white wire to white/black wire, there are no wires that color on motor. I know stator failed ohms test just wanted to check everything before i spent a couple hundred dollars on stator. Thank you

Find the 5 pin amphenol connector at the power pack that has the blk/yel wire in it. Jump the other wires leaving the blk/yel wire open. Do you now have spark? If so then test key switch/ kill switch as outlined in the sticky at top of page. If no then go to cdielectronics.com and use their free trouble shooting guide.

What color wires do you have from time base? Is this motor new to you? Could someone have put an aftermarket part in before you?
