Hello we have 2008 dodge caravan. For the past yr it has been in the shop 7 time for the same problem. It just turns off,mostly when comming to a stop but occasionally when driving. It will turn right back on. What could this be?

 

If I have to throw something at it, it would be an ignition switch. It is the most common failure according to your description. It turns off like you pull ur key out, right?
Also, do you have a lot of misc items hanging on your key ring?

 

One quick thought, When this happens did you just get fuel and filled the tank?
