Just to be on the safe side, why don't you pull all his feed for the night? If he's colicking or impacted he shouldn't eat anything. I'd leave his water but I'd take away all feed. Is he sweaty at all?
I keep coming back to colic because of the description you gave of holding his tail up and passing gas, if he's not a normally gassy horse, that sounds like colic. And the not wanting to move, pooping but it's kind of runny.....all kind of makes me think impaction colic.
Can you call a vet for phone advice to get you through the night? Do you have banamine or bute if he told you that it was ok to give it?
