Cummins n14 shuts off under hard pull

Hey everyone, I have a 2001 peterbilt 379 with a n14 celect plus. Sometimes While under a hard pull it will abruptly shut off, no sputtering just cuts off. I took it to Cummins and they ran the ecm and it showed high oil temp, they said it was the oil temp sensor so I had them replace it, they said the oil cooler could also be getting plugged. Next day I was driving going up a hill and it shuts off again. I get to the shoulder and it fired right back up no problems. I baby it to my delivery and then deadhead home. Bought a new oil cooler and oil thermostat. Ran about 2 weeks and started doing it again, same scenario, only under a hard pull. Got back home and put a new cam position sensor on and new fuel shut off solenoid. Still having the same problem. I tried pulling the flash codes but nothing comes up. I did have a problem with a dead fuel pedal, going down the road I’d hit the throttle and nothing, few seconds later it’s working just fine. I’m gonna try to make it to a peterbilt or Cummins today to see if there’s any codes. Can a throttle position sensor (peterbilt called it a potentiometer) cause the motor to shut off under a pull? I don’t know if it’s related but yesterday before it cut off on me I just happened to notice the boost gauge needle was wobbly and I’ve been watching it today and it moves smoothly not wobbly. Thanks guys

 

No check engine lights or stop engine lights come on. I’ll check in what you said. Where is the ignition feed for the ecm?

thanks, I will check that fuse out and see. Probably just replace the fuse anyways

 

I’m gonna replace the throttle sensor it’s just finding one. I’ll check the wires as well. Thank you

 

Just left the Cummins shop and it still has oil temp codes, nothing else. Could the new sensor be bad or more than likely a short in the wire or the connector?

 

I don’t know, he had a scan tool not the labtop. All it showed was oil temp code. I didn’t even think about that. I was in and out in 20 mins. I wish I would have thought about that. I’ll try to swing back by that Cummins after I get unloaded tomorrow morning.
