I know that my 2001 disco is nearing the end of its commission - it has over 200,000 miles and I definitely have an oil leak that's more expensive to fix than what the car is worth, BUT I've been able to keep it filled by checking it about once a month. I've had a P0455 code for little bit.

Today I was idling (not in park) in a drivethru line and my car just stopped. There wasn't any indication this was going to happen. I tried to start it again, and it would crank, but not turn over. Had a restaurant employee help push me to the side.

About 30 minutes later, before calling AAA, I tried it again and it started. Ran rough, but not that bad. I got home fine. When I read the codes, it gave me P0440 and P0455. Would either of those issues cause the car to just stop? When it stopped, there was no misfire (that I could detect, at least).

I checked the oil, too, and was definitely low.

I suppose that the engine dying could be unrelated to the codes, but it seems like if something like that happened, you'd get a code for it.

Any thoughts would be GREATLY appreciated!!!

 

Those codes are for evap leaks, seems unrelated to the problem. Symptoms sound like a failing crank position sensor. I might be wrong, so let's wait for some more replies before taking action.

 

 

You need to check more than once a month.

Once a week is a better piece of mind.

 

Yep, classic, textbook crankshaft position sensor failure story.

 

Sounds like a CKPS to me as well.

 

The next time the vehicle doesn't start, use live data on your code reader and see if the R.P.M's are registering on your devise when you are trying to start the rover. If no, then the CPS is bad.
