Working with the fact that you had overheating and we have discovered
that retarded cam timing can cause overheating, plus a sudden drastic
change in engine operation, I'd say that a loose cambelt has jumped a few
teeth.

It is not unheard of for the cambelt to jump teeth during an engine stop/
start cycle. Not sure why but the belt has to be loose (or severely worn)
for it to happen.

The cold start injector only supplies fuel when the engine is cranking. The
engine will only continue to run for a second or two after you release the
key if the main injectors are not working.
