Have you checked for codes? You can do it yourself.

Let me know.

I have run the codes and all it reads is code 12, Could this be my ECU?

Code 12 means direct battery input to PCM was disconnected withing the last 50 key-on cycles. If you disconnected the battery that is what it means.

Listen, I had the same truck and the same problem. I had no code to identify the problem like you. After driving the truck with an scanner connected to the engine, for a split second, my map sensor would drop voltage and the truck would die. Then it would start right back up until it happened again. I would like to tell you to try that, but I can't be 100% sure.
