Question type: Maintenance & Repair

I have a 1990 jeep 4.0 that will start and run for about 10 minutes then will shut off as if I
turned the key off.Will start again after abt 30 minutes and do same thing. Have replaced
the fuel pump, fuel filter, dist, crank shaft sensor,air flow sensor, automatic choke. Coil
tested fine, what else could it be??

What kind of mileage on the motor? Is timing off or any kind of knock condition? What shape is the timing chain in? A knock sensor will shut a motor off cold like that.

has a little over 117 thousand miles on it, timing chain in good condition, no knocking in motor. will run perfect for 10 to 15 minutes then shut off. I can force gas into the carb and it will start.


could the knock sensor still be shutting it off ? or the fuel pressure regulator?
