Meat has a specific heat of about 3.5kJ per kilo per degree, so say you weigh 70kg, that’s about 4 million joules to lose before you die.
At 650 joules per second, you’ve got slightly over 10 minutes.
My man, first of all
4,000,000/650/60=102.57 minutes
And that’s with your math based on an imaginary object. A body is going to lose heat far more slowly.
Also, you forgot one important aspect, if you’re getting bathed by the sun and spinning, you’re constantly getting heated up.

Your skin isn’t at core temp tho, so the loss rate should be lower I think

At that point, you’ll have to calculate the heat transport of the human body, and answer questions like “how long can a person live with frozen skin” and other fun questions I’m not equipped to answer.
