2005 115hp 4 stroke outboard runs perfectly for 10 km then looses power and goes into limp mode. If engine is turned off then back on again will run normally for 400m - 2km then goes back to limp

might be some electrical problem, because, Suzukis are mostly controlled Electronically, it may represent a malfunction!!
try contacting an electrition!!

My girlfriends car has just started with the same problem, a limp home from the garage, a sleep over night and als well next day, for a while... I spoke to Mitsubishi and they have told me the TPS (throttle positioning sensor) is on the accelorator pedle assembly. There PN for this is MN125791 and its circa £88 + VAT. After exhausting all other options I may attempt this replacement and will advise the results.

CODE PO120 - TP SENSOR 1 SIGNAL RANGE PERFORMANCE. CODE P1516 - TAC MODULE THROTTLE ACTUATOR POSITION PERFORMANCE. CODE P2135 - THROTTLE POSITION SENSOR 1 - 2 CORRELATION ERROR. THIS IS A DEALERSHIP FIX YOU HAVE PROBLEMS OR FAULTS IN THE THROTTLE POSITION SENSOR.

You have a very bad COP Ignition Coil,that is spiking the PCM (computer)
The spike comes back on the TPS Sensor,then the PCM doesn't see the
throttle signal your foot sent thru, the pedal actuator (gas pedal) ,so it puts the
car into ETC Failsafe,and you can only go 6 mph.

If you got no ETC Failsafe, on the bottom right side of the dash, tell me what you do have
I need all the codes,if you have a MIL Lamp on ( the one that looks like a wrench)

In your case the turbocharger is responsible for engine losing power.
The car goes in "limp home" mode!!!
After scan the EDC-15P engine control unit with a VAG or KTS -BOSCH diagnosis tool you will find this: Fault code: P1557-Turbo Boost pressure control exceeded
1. Engine stopped and ignition switch off. Check all pneumatic connections and hoses between turbocharger actuator = pressure unit for boost-pressure control, boost-pressure control solenoid valve, vacuum reservoir, EGR control solenoid valve, intake-manifold flap solenoid valve, EGR valve with throttle - part of intake manifold. Also the vacuum connection between tandem pump and brake booster. If you find something wrong replace parts. If not go to step 2.
2. Extract the hose of the turbocharger actuator = pressure unit for boost-pressure control part of turbocharger. Instead of the original hose you must place another 1 meter long hose with the same inside diameter, and then you check to inspire yourself the air from the other one extremity of this hose. The mechanical connecting rod of the turbocharger actuator must have a smooth and whole motion. If you can do that with your mouth, then you must replace the boost-pressure control solenoid valve. If you can not reach this with your mouth, then you go to step 3.
3. This is the most difficult work. The problem is that the soot particles deposits inside the turbocharger plugging the variable nozzle geometry mechanism = adjustable vanes of the turbine. If the turbocharger actuator is not able to adjust the turbine vanes the charge air pressure increase too much and ECU (engine control unit) go in "limp mode" = engine protection software. As a result the "limp home" mode engine still running until you turn the engine off (ignition switch off) and back on when the "limp mode" is deactivated, but the fault still remain in ECU memory!
4. You must be able to extract the turbo from the engine and then to disassemble the turbocharger, clean inside adjustable vanes mechanism and refit all.

Testimonial: "THANK YOU VERY HELPFUL ITS THE VANES WHAT ARE SOOTY ITS HAD ALL NEW PIPES AND THE ACTUATOR ARM MOVES OK SO ITS GOT TO BE SOOT BUILD UP IN THE VANES."
