Fuel problem perhaps?

We need more information.

Do you have access to a scan tool like FORScan?

Fuel level? If you're at or below 1/4 could be fuel intake in tank.

In addition to what the previous guys had said, also would be good to know any recent repairs/mods you have done. Original owner?

I ran low on fuel once. Did have similar symptoms but no cel. Now when the valve cover harness came slightly dislodged on 1 side I had the exact symptoms you are describing. Not saying that's it, but mighty sus.

If you have the dongle, ForScan or TorqPro. I use ForScan and don't know anything about the other. I'm a little out of date with what's available today but I use a VeePeak WIFI adapter for iOS

We need more information...

Check out the 7.3L PSD Tech Folder if you are looking for ways to solve the problem on your own.

Based on the information you have given us, I can only recommend the following links specifically.FORScanOBDLink MX+ is nice, but is costly: https://www.obdlink.com/products/obdlink-mxp/
BAFX is cheaper, but still reliable: https://smile.amazon.com/BAFX-Produc...NsaWNrPXRydWU=

There are USB versions as well that can hook up directly to a USB compatible device.

Good luck to you.

I would check your IDM and make sure all cylinders are firing. Or what 00Dave said.
