ANY SUGGESTION AS TO THE PROBLEM  

Answer
Don ;
 Hi It sounds as if you have a leak , right . I would look in the pressure line from the power steering pump , if there is no fluid puddel or fluid all over the place than it is comming from a pin hole in the line , and when you turn it gets shot out on the road till empty and soon you will have to replace that pump because it will burn out with no fluid in it. so I would look for a tiny pin hole in the line - ok .>>>>>>>
