HARD LOPE sound HELP

I have a 94.5 7.3 powerstroke. I took it camping and all was fine. Until I went to leave. I started it. It ran good for 3 seconds then died. Started it again ran good for 3 seconds then just started loping . Sounds like a miss fire or somthing. I have a new oem CPS. Going to put that in and see what happens. Can anyone help? Or at least kick my in the right direction. Thanks all

So check this video out from youtube. Mine was loping like this and it would do it in neutral or in park and my fix was the neutral safety switch.

poor contact will burn the pins, making it drop cylinders when the injectors don't fire.
