Symptoms Like this usually point to the Fuel pump.
Also these cars suffer from inferior wiring to the fuel pumps and a substantial Voltage drop is noted between the Fuel pump relay and the Pump harness.
The fix for this is a "Hotwire" Kit
Fuel pump kits with a Hotwire kit are available at numerous Buick performance Vendors but the best stuff in my opinion come from Racetronix,com
You should also change the Prom Chip in the ECM to a modern
Chip from Turbotweak.
This will improve driveability greatly.

There is a cable and motor that actuates the antenna, the cables break on these all the time.
you can get replacement cables at nos4gn.com
the passenger fender needs to be removed to access the antenna assembly.
