I grabbed the Miata to go meet up with a date. She cancelled when I was 75% of the way there. I figured I would take a nice drive through the hillsas a consolation prize on the way home. Buuuut the car started losing power at 3k RPMs. This only happened for about 3 minutes but I captured it on video.

This was full throttle. It didn’t feel like a clutch slip - more like pulling timing. I had just idled for about 5 minutes (checking my phone maps) and did this about 4 times before it stopped. Any ideas what I should look at?
