Hello. I have a 1980 CJ7 304 2100 motorcraft. The engine runs and idles great, but it has been stalling after I drive for 20 minutes or so. If you let it sit for a few minutes it will start again and idle fine, but as soon as you accelerate down the road a bit it stalls again and won't start, even if you hold the pedal to the floor. If you let it sit over night it's good for 20 minutes again. It has fuel and air (replaced fuel pump and filter) and I've played with the choke. I also wired the choke wide open to try it. I am pretty mechanically incline, but I usually work on Mopars. Could it be electrical? (something overheating, coil ect...?) Maybe float adjustment? Just seems weird how well it Idles and runs great at first. Any help would be greatly appreciated. Thanks.:???::bomb:
