What's the Name of That Book??? discussion

I was in middle school (early 90s) when this book was a reading assignment. I only remember the plot. Two men alone in the desert. One is a killer playing this hunting game. The other guy is the one being hunted. He stripped his clothes off and buried himself under the sand with only a straw. He buried himself in the sand using the straw for air. That' how he hid himself from the killer and that's how he was able to sneak up on the killer.
