Ignition breaking up at higher rpm

Picked up a reman from oreillys. Really didn't inspect it other than to check the advance plate to make sure it wasn't flopping around like my original was. And checked gap. Got a piece of heavy paper , mic'd at .009" . No brass feelys. Improvised.
It ran great a couple weeks ago, been running good. This one test drive, it just hiccuped and hasn't been right since. Don't like shotgunning parts, I've justified replacement for everything to myself prior to doing so.

Cap, rotor ,wires and plugs all less than 500 miles. Checked wires to make sure they were seated , didn't pull and inspect for corrosion though. Will check in the AM .
All the parts and effort, it's laughing at me, cuz it knows I wanna sell it. It's just being a spiteful ***** , I think.
