Here are the symptoms:

-ABS light came on, won't go off
-keeps overheating (all the way) even when full of antifreeze
-Front of truck started shuddering
-Won't go over 10mph (starts sputtering)

Once heat went down car would go faster, used a whole jug of antiifreeze in 20 miles

Check engine light is now on

Has 195k miles

 

The abs problem most likely has nothing to do with it. But still scan it. When it heats up and sputters, does it roll white smoke out the exhaust or anywhere? And noticeable antifreeze leaking anywhere?
