Sorry you're here with problems.
The OBD port is mandated to be within 18" of the steering column, but some manufacturers get creative with hiding it
. Some require you be laying on the floor with you head on the brake pedal to see it.
If you loose power without the CEL ( Check Engine Light ) coming on , then runs ok after cool down, could be early signs of fuel pump failure , and that wouldn't trigger the CEL.
