truck trouble

[X24]

1964 chevy c10 step side
230ci straight six
Auto power glide

Having some trouble as of late.
My truck will start and run (idle normal) for about 2-5 minutes, then it just shuts off.
It will start right back up and do the same thing over and over Again without fail.
A little more detail.
Thursday I cleaned up my dash a bit so I unplugged my heater switch, cigarette lighter, ignition switch, wiper motor and headlights... I cleaned around the bezels and re-inserted the harness on each. Everything worked fine mechanically the next morning.
Friday I drove it normally to work in the morning. But in the afternoon it started. While in drive the acceleration just stops? The engine stayed on but my acceleration was zero? Then the motor finally died so I pulled over and checked things out.
I noticed that my choke was still open about 1/2 an inch. Ever since then the motor won't stay on for more than a few minutes. I do have a little carb leak, and there is fuel in the fuel filter (3/4 full), battery good... Any ideas?
