82 280zx turbo... anyone know wuts wrong?

[seekNdestroy2x4]

I have been restoring this 1982 Datsun 280zx turbo for several months.... new cap and rotor, plugs and plug wires, oil change, fuel filter, fuel pump, and cleaned out gas tank. breaks are good too we just put in a new master cylinder. new alternator as well

the car starts up just fine. You can sit in it after u start it up and rev the engine as you please, everything sounds good. its an automatic.. it goes into drive and reverse just fine... trannys all good and wut not. after u put it into drive and accelerate, the car starts to take off but give it a little more gas and u hear a belt squeeling up front. the car then loses power and dies on you. it starts right back up, but when u try to accelerate and move the car dies on you.

i know the belt squeeling isnt the alternator belt becuz we changed the alternator and got that belt good and tight. i also noticed that the AC belt which runs on pullys between the alternator belts was missing.

so would that missing AC belt have anything to do with the car not wanting to accelerate? would that be the cause of that squeeling noise that starts to happen when u try to acclerate? or would this be something completley different?

if anyone knows anything about this kinda problem please let me know. i cant figure it out and i need to hear it from someone who has had a problem like this before.

thanks
