My 1998 Monte Carlo z34 has a knocking noise coming from under the hood. No one knows where the noise is coming from. The car does not lose engine compression but dies out while rolling down the street. In order for it to start again the battery has to be recharged. I dont have a battery or service engine light come on. Can anyone tell me what it may be?

Have you had the alternator or charging system tested. Would have to hear the knock.
