Default stalling ... throttle position sensor issues!?

the car has been going into rep under boost but now it runs for a few seconds and dies turn the a/c on and it dies instantly. When i scan the car with hptuners i am getting throttle position % but i am not getting any voltage. The codes im getting are :
p0103
p1120
p1220
p1221
p1514
p1516

i bought a used tb with tps sensor and it makes no difference. so unless both the tps on both throttle bodys is no good i can rule out a bad tps. I also took a reading from the plug with the key on.
A=5.v
B=0. ground
C=2.v
D=5.v
E=0. gound
F=nothing not ground no voltage (its the pink wire if that helps)

any help would be much appreciated!

The car seems to run ok and doesn't stall from a cold start but once it's warmed up and you restart it dies within seconds. I just filled it up the day before it started doing this is there any chance it could be bad gas? Any help or ideas would be great!

It doesn't stall cold but once it warms up it just stalls and at startup it's lean then gets richer until it dies.....

I'm having the same issue with my Vette. Did you ever figure out what was wrong with yours?
