I'm having issues with my msd hei, anyone else too?

[INSIDIOUS '86]

So my procomp pro billet hei that isn't made anymore killed the vacuum canister so I figured it was a good excuse to get myself a pro billet hei. My old one was great but I had a good few weeks of tuning it to get a curve I liked and the pro billet has all the features and stuff I was looking for.

No my setup runs a Mallory 6al with rev limiter which means the msd heat module is bypassed. Although I left it in the distributor unhooked just in case of a the rare event the 6al died. That way roadside/parking lot repair would be easy and I won't be stranded with no ignition. The msd distributor has my old accel super coil on it cause im pretty sure the coil that's on the pro billets are no better than off the shelf parts store stuff from what I researched

No the problem. The truck starts up fine idles and revs fine but seems to be intermittent at mid to high rpm but sometimes clears up. Never had this issue with my Chinese distributor. Then the part that really pisses me off. I can be idling happy as a clam listening to my nice lope and the engine just flat quits. No drama just OFF all of a sudden. It will do this when I'm driving in town. Any ideas?

Coil an distributor housing are grounded. I'm going to take the cap and rotor and throw them on my DD to qualify them and see if that's an issue. Could the pickup coil inside be the issue.

-thanks for the help guys. I'm. $350 poorer and my truck runs worse.
