I drove my truck home from work last evening, just like always. Got in it this morning and it started but shut back down, just as it was speeding up. I cranked it a few time and it did the same. I went in to get keys for my sons truck and tried again as I walked by. It did the same thing as before. My first thought was fuel, but I have plenty. Next thought was fuel pump, but I'm leaning more to electrical now that I've thought about it. It acted like the switch had been turned off. Any thoughts?
