Rev Limiter on 350 TBI??

Hi Guys, can any one tell me if there is an electronic rev limiter on the 310HP Preditor Motor/ 2001 350 TBI motor? If there is can I remove it? If not I still have a problem....

Once it gets to about 4500rpm, it seems to hit a wall and start to pull revs out to about 4300 then back up the 4500 etc. It is almost like a soft cut out rev limiter in a car, but lazy. Throttle is at about 2/3 and not full. Speed is about 38-39 mph.

Once run at high speed (Barefooting) and it hits this rpm, we shut down to get person in boat. Then I find the motor will start, kick over and die. It will do this untill I open the throttle and start on fast idle, then it starts ok and runs and starts fine.

Any ideas appreciated!!

Note the following parts have been replaced / repaired over the last 4 months:
Fuel filters, injectors, pump & pipes (pressure 25psi across the range). Also new sparkplugs, leads, distributer(cap and rotor), battery and cables. Also MAP and TPS, AIC. Also replaced all temp sensors, thermostats, impeller and pump.

Thanks a ton!
