Why is SQL query faster than using the VIEW...?

Experts:

I'm a little confused. I have the following VIEW created. When I run the literal SQL scrip within the view...it completes in about 3 seconds.

But when I do this:

Select *
from View [dbo].[View_Skip_Pay_Count_By_CustomerID_CompShip]

The query takes about 3 minutes....?????

Any ideas as to what is going on...? THANKS  MikeV
