HEI Ignition Problem

Hello guys i was hopping i could get a few ideas or maybe an answer to my hei problem.

i have a sb350 with a mallory hei about 8 months ago i replace the cap/rotor/module.

about a month later after that, i was driving my truck and it just died (no spark) turns out when i replaced all that stuff i pinched one of the coil wires when i screwed the dust cover on.

so i bought a new coil and put it in- everything has been fine sence.

today i was pulling out of my driveway and the truck started sputtering and cutting out. i thought it might be a moisture problem so i pulled the cap off everything is dry and the rotor looks good.

i noticed whare the carbon brush goes thought the center of the cap (underside) that the plastic was chipped- so figued that was the problem.

i got a new cap and put it on i went a round the block and its doing the same thing so i guess that wasn't the problem.

im reallllly confused now because yesterday it was runnin fine.

so what do you guys think it could be?
