Please help! 2002 S-10 Shuts off when I put in park

Can anyone give me some suggestions on what to do about my 02 S-10? I've noticed the past couple of weeks that when I put the truck into park it shuts off. This doesn't happen every time. I took the truck to the local dealer and they checked the computer, but they say that there is nothing wrong with it. Any feedback would be appreciated.
