Bad Laydown?

[Rduke55]

I'm pretty new to Omaha and I definitely need some help with my game.
$10 Omaha 8/b Tournament on Absolute. 70 started down to about 35-40.
Average stack is 2400, I have 4300 and am in the BB (100) w/ KQJ8 (suits do not matter). Five limpers including the SB.
Flop is 883. I bet out 400. Three callers. Turn is 3. I bet out 400. Same three callers. River is a 5. Bet 400 (figured kind of a blocking bet). Next guy goes all in for 3300. Next guy calls all in for 1650. Next guy folds.
I think about it for a while and fold.
Thoughts?
