Suzuki released a new version of the engine interface software earlier this year, mainly to address data instability issues people had experienced. For 2018 engines it is version 3.5.04.

I think it would be worth you downloading and installing the updated software.

Here is a link to where you can find it

I suggest that you update one interface cable at a time, you might need to temporarily unplug one from the network if your engines dont have separate keys. Otherwise, just turn one engine key to off, upload the update, then turn that engine off and the other one on and repeat. If both engines are “live” on the network when the update is selected it will try to update both at the same time and is likely to crash.

Once the updates are installed make sure that the network configuration is still correct (eg engines are still correctly designated as port and starboard.
