I have 2005 dodge ram 1500 2x4 4.7 v-8. It runs smoothly most of the time but will stop dead all of a sudden then restart. Sometimes it just stutters like the fuel line is clogged or something. After one these occurrences it misses randomly until I shut it off and restart it. Then it runs normally. We have replaced the fuel pump and drained the gas tank. Fuel pressure is normal. Any ideas?? Code it is throwing is 300 intermittent miss.
