Any chance there could be a cracked head causing issues? Even though compression was good?

 

What does that usually cost in terms of repair, worst case?

 

Try swapping injectors on cylinders 1 and 3. See if the miss moves with the injector.

 

I probably should have done that first

 

I read the tread and I think no where did I read you had chacked battry or it connections. The 10-15 minute time is just long enough for a battery to start having problems with a bad connection and hard turns could be flexing the hardware. check t insure battery is tied down well and you have a clean ground(take apart & clean). This is the easiest work you will have done so far. When electrical devices heat up there will be a voltage drop due to the rise in current.

Hope it helps

No The battery was the first thing I checked, I just didnt mention it.

 

So it turns out that injector #3 has something clogging it.... When swapping injectors 1 and 3 something must have cleared itself, the truck was working great after this...

So now I have a spare (new) injector incase #1 starts acting up now.

THANK YOU VERY MUCH YOU GUYS!!! I cannot tell you how happy I am to have this resolved!!
