Post vespa ET4 150 loses spark after it fires.

I have a 2002 ET4 150cc scooter. It used to be a rust bucket, but I tore it apart and rebuilt it. Now I’m almost there and I’m having a funny spark problem.

I have spark for one combustion. Once the motor fires, the spark goes away. I’ve searched for help here but I only find “no spark” problems.

I think I have it all wired up correctly. Ignition coil tests ok. I’m using an inline spark tester so I can see when the spark stops.

Has anyone ever heard of this?

Thanks
