engine misses and cuts out at high rpms

[Power]

I have had two problems with my car idling fine but cutting out at higher rpms. One was the fuel pump going bad and the other was a wire at the Starter Cellunoid(sp?) wasnt tightened down correctly and was arcing at the higher rpms. I know thats pretty weird but I couldnt't figure it out until it got dark because I never thought to check there. I had another problem with pitted contacts inside the dist. cap but if you have electronic ignition you should be ok there.
