Ok, if these needs to be moved, then mods, please feel free to do so.

I was towing a ~7500 lb trailer this weekend, and started experiencing a problem while pulling up grades. When I tried to maintain a speed (weather it be 50 or 65) occasionally the Edge Insight monitor would flash red and show "Load Alert 100%" and when that happened the truck lost power and would loose its momentum while pulling the grade. No DTC's were set, so warning messages or lights or anything. The only thing I saw is that when that did happen, the fuel pressure according to the Insight dropped from ~16k psi to ~9/10k psi. boost didn't change much, EGT's were normal (around 1100) it happened during the day (around 75 Deg) and at night (around 65 deg). I cant figure it out.
I changed the fuel filter thinking it was plugged, but that didn't change anything.
on the last half of the trip, I unplugged the insight from the obd2 and connected the PPE to monitor the Data logging screen, but it never did it again after I unplugged the insight.
From what I know, the insight just monitors, it doesn't alter anything except if you tell it to clear DTC's.
Anyone have any similar experience or have any ideas?
Sorry for the long post.
 
Update

So i updated the software on the Insight today and took it back out with the same load and pulled it up several grades. Not a single hiccup.
I then loaded the PPE level 2 back into it and ran it again. Still no hiccup.
It ran perfect. So I am assuming it could have been a bad batch of fuel. I did run the tank pretty low and when I filled up, then station didnt look like they sold very much diesel (especially at $5/gal while every other station was $4.39/gal. But I was nearly out of fuel and didn't want to take the chance of running out.
So from what I can determine, it was either a bad batch of fuel, or it was run so low that it picked up something in the tank??? I don't know. it seems to be ok now. I need to get some more stanadyne. I haven't run it in a few tank fulls now. If anyone has any ideas or info, It be interested to hear it.
Thanks.
 
Yeah im not too happy about it. But so far it runs good. I have to get that POS AutoZone fuel filter changed back to a baldwin. I am just gonna chalk it up to bad fuel. Thats what i get for not planning ahead. I guess i need to start looking at an aux in bed tank.
