ArrayDeleteAt() returns "Yes" when it completes. So, in your code, once you delete from the array once, session.item is no longer an array, but is "Yes". So, the next time that ArrayDeleteAt() code runs, session.item is not an array and throws the error you got.
Change your cfset to something like
<cfset tmp = ArrayDeleteAt(session.item,1)>
(I'm not sure, but I don't even think you need the "tmp =" in there, but I always do it to be safe)
