So I stopped at the store on my lunch hour, when I went to start the truck nothing happened, turned the key back and tried starting it again. The truck started right up but after a few miles the "server engine soon" light came on and the truck started running really rough - no power and it felt like it was misfiring. I pulled over, shut it off, and started it again - the light went out and it was running fine again - drove 5 miles back to work without any problems - any idea what might have caused this

Thanks
