Randomly Dying and Sputtering

[7.3_pwr_strokin]

E99 7.3L

Truck randomly dies when it's cold or when it's raining. Driving along and come to a stop and the truck just dies. Or sometimes driving along and the SES light comes on after it looses power sputters and jerks really hard. Anybody have any ideas?

SES Light? Whats that?
My truck has died about 4 or 5 times in 3 years. Not sure why. It has allways just started up again with no problem as if nothing had happened. Recently while running on the Diesel tank the truck has acted like it was running out of fuel & dying. I hit the V3 switch & she picks up & runs fine. Then if I switch back to diesel it also runs fine.
I changed the diesel filter the other day thinking it might be that, but it looked very clean as i run the V3 95% of the time.
I have been told that if the cam sensor goes the truck will just die so I've wondered if it's that playing up now & then.

Get it scanned . Most likely a Cam Position Sensor . With you saying it dies in the rain though it could be IDM , they are in the drivers fender and subject to moister issues .

It's not the CPS, already tried that one. The IDM I'm not so sure about, cause it also dies in the cold just because its cold. But water would short it and fry it I think. The cold may ease up on the resistance to the wire causing a higher current than normal but I don't know if thats it. After the truck dies it starts right back up no problem actually a quicker turnover. Got it scanned...no codes! The SES light goes off after a while. Don't these trucks store codes???

There are ( I think ) hard and soft codes . Hard ones stay stored and soft are only on while the issue is happening . Strange that it starts right back up . Man could end up being a tough one . I hate random stuff , it's hard to find .

This is getting bad guys. I got the truck scanned while the SES light was on and the scanner said no codes...so I tried a different scanner...same thing. Any body out there have any suggestions. Not a CPS. The battery light does come on when it dies??? But as soon as it dies, I can immediately start it back up with no problems? Only have these problems in the cold and in the rain.

I had a similar problem. I have a in tank fuel pump and I had to replace that pump now it runs great

I am having the same problem myself. It didn't start until I was up in Lake Tahoe this past weekend. I started it up and noticed right away that it was running funny. I thought that it was fuel gelling. Since then I have ran several tanks and it does it still. Not as bad as the first time though. Once it warms up it's like it never happened.
