>The only change was to remove the Street name. So, what is causing this exactly. There seems to be some verification on the Street name field if I include it such as taking 56 seconds but I would get an instant result if I do not include it. But, I need to have that field in there so I need to find out what is the factor here.

Just a speculation, but have you tried to move Street to the first place in the field list? Is this field still a culprit?
If it's not broken, fix it until it is.
