What's wrong with my car?? It is making a LOUD noise from underneath.

What is your question?

My oil light came on and started flashing, a few minutes later a loud clanking or maybe more like a THUNKING like something had come out of place and was just tumbling around. sound from underneath started. I slowed way down, (I was only going 35-40 at the time) less then 20MPH, still clanking. stopped at red light and car died. I had to really pump the gas pedal to get it going again. I checked the oil and there was barely any in there. I just had an oil change a couple weeks ago. No oil puddle or signs of a leak. HELP!!!!! No signs of anything broken, None of the engine warning lights appeared after the initial stall at the red light.

What makes this problem better or worse?

I don't even know where to start...

How long has your 2004 Acura MDX had this problem?
