Mark,

Has the carb been apart for any reason, jets-etc ..?
Did you have a stumble/miss with 3 lbs of fuel pressure when you first started ? Sounds like maybe float or needle is sticking and fuel is bleeding by ? Is it clean driving around in pits & on starting line....? Maybe Danny will jump in if he is around ? Top of 1-2
shift usually points to flapper valve adjustment ? I would take carb
apart and check over really good, look for dirt or something in needle & jet area and make sure things haven't fall into bowls ...
Good Luck, keep us updated & talk to Vic Santos, he's very good with Q-jets.........
