This all started after my battery died. We jumped it then the car ran for an hour and just randomly died. We replaced the fuel pump and cam/crank sensors. Check connection. Checked voltage from computer. We just cannot figure out what's wrong. It will run for about an hour then start sputtering and jumping then as soon as you hit the breaks it dies. It will run idle in the driveway for over an hour but as soon as you hit the gas or shift it dies. It will turn over again but just sputters for about 15 seconds and shuts off.

At the time it happens, you need to monitor fuel pressure, spark. One of them is failing and you need to track down why.

I have had these issues in the past and found bad pcm, but before you go there it needs to be confirmed as it is an expensive repair.
