I have a 300M that continues to give me problems. It starts up fine and runs fine for about 15 minutes, then it will start to miss and sometimes stall, it will always start back up though. I have changed both speed sensors, the cam sensor and the crank sensor. Can anyone tell me what is happening?

 

Any codes?
Could be a clogged fuel filter. Won't let enough fuel through except for a short run.
Maybe a bad coolant temp sensor. Without codes, we're just guessing.

 

do u know how to check for codes? if u dont just ask, thats really what we need
