Unfortunately, you have an provided me enough information to diagnose this problem. It could be a clutch issue, where the clutch is slipping, if you have a manual transmission. It could be an issue with your automatic transmission, and the fluid inside, if it's slipping before engaging. Off the top of my head, it doesn't seem like it would be an engine issue, the more of a transmission issue. I'm going to copy this question to the forum, and if you can add some more additional information there, perhaps we can help further.
