The car will start and run but sometimes after you shut it off it won't start again, but after it sits for a couple of hours it will start back up.

Hi,

Based on your description, it sounds like a faulty crankshaft position sensor. When they begin to fail, they are adversely affected by heat. Once it cools off, it will begin working again.

Here is what I need you to do: When it won't start, see if it starts for a couple of seconds using starting fluid. If it does, then we know it's a fuel-related issue. If there is no change, we need to check for an ignition spark to the plugs.

Here is a link that explains how it's done:

Additionally, here is a link that explains the symptoms related to a failing sensor. Take a look through it and let me know if you feel it mirrors what you experience.

Let me know what you find.
