Pretty sure at this point that it was the inquiries.
It could be the inquiries but you really haven't demonstrated a need for a CLI. If you put $2600+ in one month that would be a different story, but over two months...
Every CLI I've gotten was after a few months of exceeding the limit in one month and having to pay it down to use it again. So in the months leading up to your next request make sure you run $3k a month through the card. When you call explain to them it's too inconvenient to have to pay your bill several times a month. Also tell them your credit is important to you and in order to protect it you need a higher limit to keep your utilization below 30%.
Others will no doubt have differing opinions and of course YMMV.
