Your battery is no longer holding a charge. Replace the battery and make sure it's fully charged. Make sure the car is in "Park", turn the key off and on a few times to see if the key interlock disengages. These cars can do really weird thing if the battery voltage is even slightly low or the ground is bad.

Not sure where to look but it sounds like ECU is not sensing your car is in park.
Could be a bad sensor on the transmission gear selector.
