We wonder whats broken.Looking @ the engine run, it seems just fine for 10-15 minutes.THEN it begins to spit,sputter & rev up & down(when given gas) black smoke comes out if you try to keep it running by giving it gas.It dies & wont start again till cooled off.Autozones diagnostic had no code to give.It just said running rich.What could possibly be wrong?
