2 stroke. will have spark then loose it

[hvactech]

I am tryin to figure out this crazy thing. i bought it and it wasnt getting spark, so i put new plug and stator in it and it fired up and ran great. then went to go start it again then no spark, let it sit for a few days started looking into it and found that it had the remote start, so i pulled it off and did the bypass (green and dark green wire together) and it ran fine. rode it 10 miles around town, filled it up stoped a few places. got it home parked it then a few hours later went to take it on a spin and no spark.

Not sure what to do next, CDI or kill switch or what

Checking all your grounds,checking the spark plug boot, that the connection inside is ok, and make sure all the connection in the switch are not loose,making sure you pickup is screwed tight and gapped right are all thing you could do before spending money on a cdi

Id probably replace the Ignition Coil before the CDI
