Lose spark when throttling up from idle

[Troubled boater]

Hey guys have a problem with a 1991 40hp evinrude loses spark when throttling up from idle or cuts out very speratic. Ok a little history the motor has set for several years so I've cleaned and rebuilt carbs new tank fuel filter gas pre mixed did away with vro and new fuel pump check temp senser but still starts and runs great at idle but anything above that spark gets Speratic or non at all sorry so long of a explanation but wanted y'all to now the facts thanks and any help would be appreciated

Check the wiring coming out of the mag plate for being broken or loose.

Thanks for the response I am assuming mag means magnet under flywheel

Yes, the plate that moves when you advance and retard your timing.

Ok thanks don't think it could be the rectifier or the coils I wouldn't think it wasnt the rectifier for its just for the charge system if I'm correct and the 2 coils are cutting out almost simultaneously I believe according to my spark tester and timing light I may have answered my own question but I find second apinions helpful
