I have seen new injectors crap out. You could try swapping injector with the one next to it and see what happens

I could try that. The old injector that was in it was only 2 years old and was a brand new ford injector, I put a new ford injector in and it does the same thing. I am leaning more towards the injector harness because it is intermittent.
