Question: Where is my gasoline going??

I have a 1991 chevy s-10.
While my gas gauge and oil pressure gauge don't always function properly, I've kept track of my gas usage by miles since I bought the truck. Recently, I ran out of gas when I KNOW I should have had 1/4 to 1/2 a tank. I thought maybe someone siphoned it. I put a half of a tank in it, and my gas gauge clearly showed a half a tank. I drove the truck home, and parked it showing a half of a tank on the gauge. The next time I drove it, several days later, my tank was empty. I'm sure it's not being siphoned. I am getting a slight gas smell to my engine oil, but when I changed out my oil, the correct level was drained, no extra.
My question I guess is what is going on here?? How am I loosing gas when the engine isn't running??
Is it possible for my fuel pump to keep running and pouring gas into my engine block? Would a bad gas cap and high ambient temps allow that much gas to evaporate? How do I troubleshoot this? I am pretty handy

PLEASE HELP

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
