When drilling through hardwood, I suggest going at low speed and using cobalt drill bits they are tougher than your ordinary drill bits and are designed to go through the toughest metals. Cobalt drill bits are more heat tolerant and have excellent wear resistance.
One of the reasons your drill stops drilling is sometimes your drill bit has hit a very dense part of the wood. Another common reason is that the tip of your drill bit has deformed due to heat and is no longer catching on the timber. It is important to take a break when you've been drilling and are not making progress.
One helpful technique when drilling through hardwood is to start with a small bit to create a pilot hole for the bigger drill bit to cut into. - EricL

I find that when putting screws into hardwood the trick is to scrape the thread of the screw through wax first. You could use slightly dampened soap, but it can cause some types of screws to rust. Bees wax gives right amount of softness and sticking I found, which you can buy as sticks, blocks or in a tin. You won't need much. - TedBear
