2016 Vortex 203 - Multiple misfires

My 2016 Chaparral Vortex 203 has diagnostic PO300 and PO301 (stbd). This happens a few times a year and my tech changes the plugs and it runs fine for a short period and then does the same thing. Engine dies down, smokes, and have to limp back to the dock. Another problem is it started to not start. Turn the key and the dash would start up but not the engine. After a few times or longer turning the key, the engine would start. The tech installed a new relay, it worked for a short time but is doing it again. Can anybody give me some idea what the problem is with both these problems.
Thank you in advance,
Rob
