I solved this problem by recreating the stored procedure!
Just a simple DROP and then CREATE stopped the timeouts in my case!

A genius friend of mine said, "Going through ASP uses a 'cached' execution plan, which is not very efficient. Try dropping and recreating. This does suggest your stored procedure could do with re-writing to make it more efficient, as it could happen again."

Since the proc was running fine when tested with SQL Management Studio, I assume that does not used the cached plan, but ASP does.
