William,
The first thing I would suspect is vapor lock. Try
dumping in some gas treatment and run it around for
a while. I definitely would replace the rotor and
any other suspect parts. As others have mentioned,
disconnect the O2 sensor to see if it make a
difference
(after warmup). Other than that I'd double check all
electrical connections as well as the air cleaner
connection to the thottle housing. Get that rotor
replaced, though. You may have found the problem
yourself...
Good Luck,
Steven
