My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The knocking noise may be a connecting rod bearing failure or crank shaft main bearing failure which will put strain on the crank shaft turning and in this case the engine can stall out like this here.I would have the knocking noise checked into further to see if the source can be located and then from there repaired to correct this issue here.In some cases if this is the crank bearings failing this can require a complete rebuild or replacement of the engine.
Thanks Pete
