Seadoo limp mode help

[Canadian06]

I have a seadoo challenger 2000 with a 240hp merc M2 jet drive and Im having some trouble with it going into limp mode.

if I launch the boat, start it up and cruise non stop it runs perfect. If I turn the motor off then start it again it goes into limp mode until the boat is taken out of the water for a few minutes. It will run fine if relaunched.
any Help would be appreciated

I’d start with the low hanging fruit: plugs, fuel, fuel filter, air filter, oil, batteries, ground/electrical connections.
