Stall and P0604
My wife was driving 60mph when she said the vehicle felt like it lost power then it died and she pulled off the road. When i got there I hooked up the scanner and the only code was P0604. It was currently running SCT X3 65hp Tow program. I started it up and everything seemed fine. I then set it back to stock and drove it home 25 miles with no issues. Had been running this program for about 6 weeks and have pulled our camper 300 miles during this time with no issues. Should I be concerned? Which came first the code or stalling pulled the code?
I thought it said P0604 when I check with my SCT but when I got home and checked with FORscan it pulled P0603.
Thank
Eric

Looks like P0500 is the only possible critical one. Which sensor would be causing this and where is it located?

The vehicle speed sensor is in the rear differential. Is your speedometer working?
The most common issue when getting that code is a damaged wire. If wiring looks ok, then check the resistance of the sensor - should be 800-1800 ohms. That said it could be a wiring issue internal to the harness, OR even low system voltage can cause it.
Not sure what would cause this one:
U2016 - 5R110W Code (DTC) : Signal Link Short to Ground (Non SCP) / From NGV Module

What is the battery voltage when the engine is running?
We had our 6.0 stall while my son was driving, but started up again. Only to not start when he left work a couple hours later. Turns out battery terminal had not been tightened when working on it earlier that day.

Voltage was good but that is a smart simple check. Thanks

So I replaced the rear end speed sensor this weekend after it tested around 2k Ohms. Drove it to church and back on Sunday and to work and back today. Then heading back to work after lunch I felt it loose power a couple times. I decided to turn around as I was only about 1/2 mile from home. I accelerated back up to about 50mph and it lost power this time for good. I shifted into neutral shut then ignition off and back on and then it started but died on the 2nd time I started it and revd it up a bit. Shifted back into drive and drove home. No SEL and no error codes.
How in the world do I troubleshoot this problem?

What I am planning on doing moving forward
1. Check fuel filters.
2. Drive with datalogging FICM Main Power, FICM Sync, ICP and ICP Voltage using Torque Pro....is there anything else to datalog and how often should I set the logging interval?
Thanks
Eric

Pulled the filter at the pump and it looked brand new.
Pulled the ICP plug while it was running and it shut down and threw the code for low ICP.
Plugged the ICP back in.
Drove it to work today and here are the data logs.
Everything looks great and no issues. Now just hoping it dies while data logging and it actually shows something useful.

I am questioning fuel pressure. I currently have a gauge hooked up to the fuel filter cap and have read its best to have it after the valve. Does anyone have any pictures of how/where to install this?
Thanks

Thats good. I had read that if the filter was plugged or that there is a valve after filter that could be faulty and give false readings to what the injectors are actually seeing and the gauge should be at the back of the heads to know exactly what pressure all the injectors are seeing.
