Car bogs down like its out of gas

Hey guys I'm having another issue i noticed a few nights ago...

I just bought a new Holley 600 dual feed carburetor. It was running great when i first put it on. The other night, I got on the freeway and the car started bogging down once i hit like 45mph. I pulled over thinking i was out of gas, and my fuel tank was still full. Got in my car, and started my car with no problems.

I've been having the same issue for the past 3 days. It got much worse today on my way to work. It died numerous times after dying t 45mph. I couldn't keep it running enough to even stay running at 25mph! :mumum: I checked to make sure the choke was staying open when warm, I checked my ballast resistor wire to make sure it wasn't rattling off the post, (it was kind of loose so i put a new end on it) Does anyone know whats going on?
