engine stalls at idle when steering wheel is turned

[rowleybd]

So, my first weekend to have the 69 out this spring and everything went pretty good until it started to stall at stop signs, stop lights when it was idling and I turned the wheel. This truck has power steering and it feels like it is working, but the load from the pump is causing it to stall???

I let the truck set for a bit and in the driveway I started it up, good there. Idles good, belt ok on the pump. I reached in the window and turned the steering wheel......stall.

Anyone have this issue? Help Please!!!
