This scenario (below) is covered by 3 U.S. Code 15 - if the house and senate don't agree within two hours, the official slate remains in place. Tie goes to the official electors. There is no "running out the clock" scenario to reach a House vote on the President.
"The debates in the House and Senate over which set of votes to accept could be stretched beyond the two day limit using several different tactics, such as debating each individual vote for two hours rather than the whole set.
This, in one interpretation of law, sends the decision for who is elected straight to the Senate and House."
