Possible fuel delivery issue...maybe the pump is going? I suppose if the TPS had a dead spot or a two it could cause it...MAF could if its dirty like Ron said...
if youve got a schrader valve on the fuel rail (i dont know if LT1s do or not)...put a fuel pressure gauge on her while youre driving...and watch what happens when it starts to buck and what not.
And I don't know much about opti-spark either but couldn't that be a problem?
