I apologize in advance for laughing out loud when I read the subject line of your post. But from experience with my 1997 Caravan, I just couldn't help it. I am an owner and not a mechanic, this reply is based on experience and no technical knowledge but I thought it maybe of help just so you know you are not alone and not going crazy. My 97 caravan we affectionately and sometimes cursedly refer to as "haunted". It has been that way since we drove it off the lot brand spanking new with 9 miles on it and is still that way today! I had the very same thing happen to me. I was unloading sports equipment at the front loading zone of the facility, keys were in the van and van was running. Sports team eagerly awaiting me at back hatch for their respective equipment. I exited the driver's seat and for some reason, in an effort to be considerate and let others have room to enter loading zone I shut the drivers door when I got out. About as I was passing the back of the sliding door on the walk to the back hatch, I distinctly heard the sound of my vehicle locks engage. I thought, "no, couldn't have been, the keys are in ignition (can't lock) and. I'm sure of that because vehicle in fact, is still running" (as I look to see the exhaust coming out!), But, sure enough when I get back to driver door to re-enter, I can't. I check each and every door - locked! Fortunately the locksmith responded immediately and I hadn't left a child inside! Moral of the story - never assume the safety features are going to work as they should and always take keys with you as you exit driver seat!
Seriously though, I think I would have electrical system tested, they may actually be able to find your problem.
