I'm not sure I understand what is happening. When the engine revs, does it stall right after it revs? Is the check engine light staying on? Is it at all drivable?
What I would suggest is to check for diagnostic trouble codes. Here is a video showing how it's done:
Next, let me know if this started all at once. If possible, record what is happening and upload it for me to see and hear. It may help me diagnose the issue.
Let me know.
