Why is my Rev limiter kicking in?

2008 23LSV - monsoon 340,  700hrs, 55oil psi, 170 temp, 13.8Volts, all normal when running.  Start & drive fine approx 1minute, then Rev limiter kicks in holding engine below 3000RPM.   What am I missing?

emc can limit rpm 

iirc there are two temperature sending units.  one is analog for dash and the other is a switch for the ecm.  if the ecm thinks it has not yet reached operating temperature it will limit rpm.

Thanks, it is firing all 8 cyl's then drops into limp. I'll check fuel pressure and change fuel filter just because.  Code is a 'ghost', it alerts 'service required' but clears on red-button. I'll take to shop next week to see if any codes recorded.  To be continued! Thanks again all

Update on cause of this issue :  I had codes read from computer and i was had an active "Cylinder 8 Mis-fire" code, and several latent sensor codes from when I disconnected all other sensors while testing (O2's, MAP, Heat sensors).  I pulled Plug #8 and it was cracked and very likely mis-firing.  Changed out all plugs, distributor and rotor and the boat runs correctly ..... HOWEVER it still throws a "service required" signal on the screen every 90 seconds (tested and verified 10 cycles).  I will start a new discussion on this as it's a different issue.    A bit more context on the rev-limiter issue.  the mis-fire code put the boat in "limp-mode" which allowed the boat to run up to 2950 RPM's but not above.  Thx for the feedback and I hope this helps someone else.
