Advice needed asap.

Columbia glider 12.7 Ddec 4.
So I was driving along in ky and it seemed my fuel was not getting to engine? But than it stopped after a bit.
My make stopped working just a few minutes after this. I wiggled brake and clutch pedal, but did not help.
Than as I went to turn off onto off ramp in Oak grove, KY, my rpms when out of gear were staying at 1500 rpm on its own. I had to turn off truck and restart engine to park.
Is this a fuse, or sensor, or ECM issue?
I am going to unhook batteries and see if that helps. Even right now at high idle set at 1000 it keeps going to 1500 on its own? This is not a dpf truck. And it is a manual 10 speed. Here is the last ecm trip report. The ecm did not have much information as it should have had. Seems fishy.
I also posted this in the tech forum.

 

I took off of idle and tapped hammer but it climbed on its own still to 1500.

 

I have started engine after battery unhook. And now make a are back ,and idle is holding at 1000. Guess I'll take a go at it.

 

It's back to normal right now.

 

Has not happened lately. I do believe it's an programming ecm type issue.
