Question about 1985 Jeep CJ7
I have a 1985 jeep cj7 4 cyl and it will idle just fine for alittle while then it dies out and will not start again for about an hour or so. I changed the plugs , rotor / cap and fuel filter .
If you haven't had any luck yet, I suggest that you #1 replace any rubber fuel lines that are obviously bad or even questionable. CJ's had mechanical fuel pumps mounted on the side of the crank case which ran off the cam. This means that there is no pump in the tank and any fuel lines leading to that pump will be under a vacuum. If those rubber lines are wrong kind, old or almost kinked they WILL colapse under the vacuum and temporarily shut the fuel off. #2 However, in your case it sounds like the little screen filter on the pull tube inside the tank is probably stopped up completely with debre, that's why the motor dies and won't start again. If you drop the tank and remove the screen sock from the end of the metal tube that may solve one problem. If you do this though, I suggest that you put an inline filter somewhere before the pump.

Check an see if you have crank shaft sensor it should be around the bell housing lip where it mate together ...look for two little wires going there...it cost about 50 to 100 $ easy to change...
