If it only stalls in gear, then I'd have to second the Torque converter
lockup. there should be wiring at the brake pedal you can disconnect
and then drive for a while which will prevent the lockup from happening,
which if it's the cause, will prevent it from stalling.
The wife's Beretta has had this problem (TH125.) The solenoid starts to
stick after a few years and doesn't unlock the torque converter when you
stop, so it stalls the car out. It slowly but surely gets worse and
starts to happen more and more. One way to tell is when you're driving,
tap the brake - the rpms should pick up by about 200 when you hit the
brake as the tq unlocks and then the rpm will drop back down when you
let go of the brake as the trans locks the torque converter back up.
That said, I just solved a driveability problem on the same Beretta...
EGR valve. The car set no codes and would idle like crap - like a 69
Camaro with a big cam. If you stood on the gas, it ran great. I threw
plugs and wires (worn plugs and cracked wires) at it, then tried
cleaning the IAC - no change. Went to the junkyard and got an IAC and
an EGR while I was there. Also checked the va**** canister and the PS
switch to see if it was mucking with the idle. Replaced the EGR and all
done.
Also, your car is OBDII, so a good scan tool might help - not just a
code reader, but a scan tool. It can show you stuff to help diagnose
the actual problem, like the computer thinks it's -40 outside or
something really weird and it's trying to compensate...
