01 f350, 7.3, zf6, T&S 6 position chip with their canned tunes, on the low ("+40hp") setting, 489xxxkm.

Was fine yesterday, jumped in this AM and had a CEL. Started and ran fine, but had a light. Drove my bush truck to work, and came home, plugged in my cheap ass code reader and got nothing. Remembered from the last ford I worked on that I could start it and look at stats as I drove, so I started it and plugged the reader in. A minute or so later it died...but the CEL was gone. Starts and runs fine, test drove it, normal operation in stock, high idle, or +40 positions on the chip.

What the fuck was that about????

Do I have a sensor shitting the bed? Where to start looking? I've reached out to see if anyone has a scanner that will read the codes on this, as I've read that most cheapo ones won't.
 
Get yourself and OBD adapter and the Forscan app for your phone, and use it to read the codes and monitor. There's a code in there, and no one is going to be able to hazard a worthwhile guess without knowing what it is.
