Ended up one of the springs on the dist was bad or broke... was not advancing as it should have. replaced the whole distributor with a:
PNX-D200800
Distributor, Marine, Plug and Play, Magnetic, Mechanical Advance, Black Cap, Chevy, Big/Small Block, Each
(Mfr. #: D200800)
Ran like a champ after that.
If you can take your distributor apart check for any broken or bad springs.
What is your timing set at?
