2002 Honda Odyssey 02 Honda Odyssey Engine Shuts off

I have a 2002 Honda Odyssey. I have never had any major issues with it. It is at 109k miles right now. However yesterday, my wife was in the process of pulling the van our of our driveway, and when she shifted from park to reverse, the engine died a second later. Then she shifted back to park, started up the engine successfully again, and then shifted over to drive and the engine died a second later.

When I got home I repeated the same process and had the same results. I even let the engine run for 10 minutes before attempting it again, and yet the same thing happened.

I called my local Honda Service Shop and they said they were unaware as to the cause.

I appreciate any advice. Thank you!
