I have a 2005 f250 5.4L with 130k miles on it.


The engine keeps randomly shutting off. Seems to happen when we are slowing down or stopping (foot off accelerator)/ It's been to the shop and they did a bunch of work (I will attach the invoices with the description of work) and it's still shutting off. I had another mechanic come out and look and he couldn't find anything wrong while it was hooked up to live data, however he only hooked it up while the truck was on and sitting. He did say he saw the rpms drop and the truck acted like it was going to shut off, but it didnt. It also seems to happen after it's been driven for a few minutes or even up to over 30 minutes. The mobile mechanic suggested replacing the fuel pump and the crank sensor. Not sure if either of those items wouldbe in line with the symptoms.
