What was engine temp during all this? Sure sounds like an overheated engine trying to seize.

I am with JB, however I hope we are wrong.
Time to start with the basics.
test starter voltage, search the forum for V drop test. test spark,search again for a home made spark tester.
test compression.
if the spark and compression pass move on to fuel.
I dont have my stuff with me here in caracas so a bit more info would help. is this a 3.1L motor with efi or a 3.1 with carbs?
