1988 evinrude 200 xp electrical issue

ok so I basically tore down my whole motor and cleaned and replaced all gaskets. has new stator trigger coil and powerpack. carbs cleaned and rebuilt. new throttle cables/ sync and link. even psi on all cylinders. good spark.

now the problem. motor started up and ran the best it ever has. started going at WOT and after a short while motor starts to "surge/pulse" like it starts running on 3 cylinders. throttle back down and take off again to the same thing. keep trying and eventually motor barely stays running. let motor sit for a little bit and try again and same thing happens( runs on all six for a little bit then starts running on 3 after motor warms up.) when its running on 3 I tried to kill motor and it stays running. pulled kill switch and nothing happens. did some digging and found that it could be a diode going to powerpack?? any tips would be great! thanks

Sounds like an ignition problem. Put a timing light on each cylinder when it happens and see if you're losing spark. If you are go to cdielectronics.com for trouble shooting procedures.

Could be a bad pack. Follow boobie's suggestion on troubleshooting. Once your testing leads you to that conclusion, check to see if there is any new factory warranty on it.

Also check shift switch and shift diode.......
