Hitting a wall on hills.

[indysteel]

It sounds like you're hitting the hill too aggressively and then running out of steam and gears. First off, stop looking at your speed for the time being. Second, drop into your smallest chain ring as you approach the hill and use a cog that allows you to spin comfortably. Don't spin wildly, but also don't attack the hill. Maintain a steady and comfortable cadence as you begin the climb (say, 75-80 rpm). Breathe. As the pitch goes up, switch to easier gears as necessay. Don't look at your bike computer. The point of this exercise is not to speed up the hill; it's to get to the top without blowing up.
