    From Kirby Brooks@21:1/5 to All on Wed Jul 20 05:26:37 2022
    This engine developed a new problem that our mechanic has been unable to fix. When starting the engine cold, the engine will run for 11-14 minutes and then cut off. It's like I turned the ignition switch off. the engine will then restart and run for
    another 4 minutes or so and then cuts out again. It will start right back up. Our mechanic has replaced the coil, all sensors, dist cap, plug wires and plugs. He even bypassed the whole front end (iginition, cut off, etc) and it still cut off.

    Any suggestions?

    Seems like the only thing your mechanic didn't check for was fuel delivery.

    Put a pressure gauge on the fuel rail. The kits are cheap. About $35 for
    the Bosch gauge on Amazon. Most likely the high pressure pump.

    Check these first. fuel tank vent screen, crimped or collapsed
    fuel line, fuel filter, output of low pressure fuel pump, air
    leak from any of the above.
