New to us 2022 GS24 won't start

[SkiToday]

Got it back today with a new throttle base. Time will tell.

[SkiToday]

We had the throttle base replaced. Ran it probably 5 different days (pretty short sessions) and all was good. Last run tonight same thing. Won't start.

We also replaced the starter relay. Did talk to original service center and they had no record of starting issues from last owner (i do believe them).

We did have the dealer put a new linc screen in before we took ownership (under warranty .could that have caused the problem? Where do I turn next?

When our current dealer took it in before we had it, the dealer also said some of the harness in the bottom of the boat weren't secured and the engine needed to be realigned. They did fix those things. Could either of those be causing this?

Thanks much
