Engine is backfiring intermittently. Is backfiring through exhaust. Has new fuel filter and checked all points on distributor cap. Before it backfires it will lose power and after it backfires you can let engine cool and it will not backfire for approximately forty five minutes then it will start again. Have not checked fuel pressure. What would be some things that would cause this issue? Tired of replacing parts.
