Ford windstar Squeaks then stalls

Ok, Help me here...
Ford Windstar 1st she squeaks fairly loud then stalls, no check engine lights nada, no codes showing 0...
at the 30,000 all belts done ect... the recommended detail from Ford.. all done 600.00 dollars later this???

OK, help me out please:banghead:

Try a heat / Air conditioning setting at the "Vent" position.
IF the problem does not happen....then it is likely the A/C compressor causing the problem.
The A/C cycles in many settings other than A/C.....but not at the Vent position.

If that has no effect, then try to determine if it is when you are turning the steering wheel when moving very slow, or not moving at all.

it squeaks then stalls, when at a slow move 5 mph or stopped. No A/c on or Heat....

the A/C compressor would make the windstar stall? if I unplug the electrical connector to the a/c compressor to bypass this and this is not it what could it be?
