Where are you located? Maybe someone who has a t1N scan tool can help you pull the codes.

Try leak off test. You may have bad injectors.

Well, what happens at (or near) 192F?

The thermostat opens to allow coolant flow. (should be circa 180F)

Do dash lights (including Chk Engine) come on when it quits? Do they all go dark?
