vapor lock?

Okay, I thought I'd fixed this, but it just keeps coming back. When I start the car, it is fine...but after the engine gets good and warm, after 10-15 minutes of driving, i'll lose all power at thottle. If I sit in the driveway it is slower to rev.

Vapor lock maybe? It has no issues starting back up, it just has no power.

doesn't sound like vapor lock, with vapor lock you will run out of gas and die. Think you may have to look elsewhere.

Is the choke fully opening when hot?

Worth is right. (That's 2 this week). Vapor lock will kill the engine until the air bubble is cooled. I have had 2 Mustangs get on top of Pikes Peak (14,110') with the temp gauge pegged out and no lock. My weed eater did vapor lock last week however. Took 15 minutes to restart it. Choke??????????? Yes, maybe. Worse case may be the thing is trying to lock up on you. How is the oil pressure?

adjust your carb.

Sounds like the idle cuircut is fine. No other adjusment will help when accelerating. Maybe accelerator pump diaphram or vac. leak.
