Engine died down at high RPM.

Thank guys, It's a 1986 150hp 6 cyl Evinrude.I'd be happy with either the power pack (power pack looks to be just under 100)or switch(havn't looked that one up yet).
When I had the engine running at idle back at port I pulled each wire and I could hear the spark clicking and feel the engine bog.It would right itself once I plugged it back in.
I never held it to the block though.
Steplift, are you saying do them one at a time, disconnect then reconnect and move on, or disconnect one side leave it off then disconnect the other side?.
Thanks again guys.
