P0351 code is flashing on a 2002 Dodge 1500. It just quit on me what does this mean?

Question

I have a 2002 Dodge 1500 and it just quit on me the other day. In the past it has did this twice and it has always been the ignition coil. I went and bought a new ignition coil and put it on, but it still wouldn\\'t start. So I turned the key three times to bring a code up and it flashed P0351 and P0300. Was just wondering what the heck is wrong this time and why this keeps happening? Thanks for your help.
