More I thought about it, it’s more then likely a intake seal or something that is warming up and sealing itself. Maybe a worn sparkplug or plug wire going bad. A clogged cat gets worse when it’s heated up normally 🤦😄 should have thought of that. Could also be as simple as the mass airflow censor on your air intake might loose or dirty. Advance auto or auto zone will be able to tell you the codes it is showing for free and would help narrow it down. Hope this helps
