Ignition Problems 912ULS

I have a 912ULS engine on my RV12 with 390 hrs on Hobbs

 I had an issue with hard starting and sometimes not starting at all. It had never had the carbs overhauled so I sent the carbs to Lockwood for an overhaul. When I replaced the carbs still having the same issue. So I replaced both ignition modules. Now it starts right up but when I do the lane checks it dies when I turn off Lane 2.

Any thoughts on what to check next?
