[The Meg] I've just been swallowed whole by this massive shark. How quickly do I die in its stomach and what kills me? Do I suffocate first or am I dissolved by stomach acid?

Sharks take a very long time to digest food, with undigested food inside them up to 18 hours later. Given the size of a Meg, you probably won’t suffocate until your tank runs out of air. (I’m assuming you’re in a dive suit.) 

Your biggest problem is you’re likely to be eaten by a normal sized shark swimming around in the Meg’s belly with you.
