The most common cause of this is a crank sensor. These are called hall effect sensors and when they get hot they fail and then when they cool down it starts working again.

Here are a couple of guides that gets into more detail:

Unfortunately we don't have a manual for your vehicle so I can't give more specific information but I would replace the crank sensor and then retest. Let me know if you have questions. Thanks
