Stump the Chump reborn

[Bob M.]

OK...time to get this train rolling again. Here's the first installment:

PLAY: A (no TOs remaining) trails 13-10 with 0:10 left in the fourth quarter. It's 4/5 on B's 22. A15 runs and is tackled at about B's 17 where the LJ notices that it's close to the line to gain. He stops the clock with 0:03 remaining. Umpire flagged B32 during the play for an incidental face mask at B's 20. What is the next down, distance, and more importantly when will the clock next start?

OK...let's allow the FED guys to answer this one first, and then we'll get the NCAA guys to weigh in. Oh...and of course our Canadian brethren too.
