P2149 Fuel Injector Group 2 Supply Voltage Circuit

I was pulling my 38' enclosed trailer this morning and my check engine light came on with this code. (P2149)

There was a pop that sounded like the waste gate opening momentarily when it happened.
I was pulling a grade, and was running about 25 lbs. of boost at the time.

What is this and how do I fix it? The truck is still running just fine. It didn't seem to affect anything as far as I can tell.

I have to pull this trailer again this evening. Do you think I am safe, since the truck is still running normal?

This is the only code that it is showing, and I was running my Edge Juice w/ Attitude on #2 when this happened.

How do I clear my codes? If I unplug my batteries will it reset the engine light? Should I try to clear them and see if it comes back?

This could be true. I am running the stock fuel system, and was leaning on it pretty hard. Maybe it is time for a FASS!

I took it to the local Checker, and they cleared the code for me. So far it has not come back. I will let you guys know if it does.
