02 montana quit running

02 Montana quit running today while driving down the road....took a little while but it did start back and ran for a little while further and quit again....checked the fuel pressure while driving and it stayed around 55 lbs even when it quit again it still held pressure....changed fuel filter....and changed crank sensor.....but did not fix my problem...kinda stuck of where to start looking....any ideas

You need to know if you are losing fuel or spark. Check for spark when it dies. Also, you can shoot a little throttle body cleaner into the intake to see if it will attempt to start. Then you can go from there. It doesn't sound like a fuel issue, but you won't know until you see if you have spark.
