I have recently replaced the fuel pump and water pump on my van, but it is still shutting off after running for a period of time. After sitting for awhile it starts back up. I was wondering if it is something electric or a sensor. Please can you help me out.

Good evening,

I would start by cleaning the throttle body and doing a relearn. Carbon on the throttle plate will cause stalling.

Also, check and see if there are any codes stored.

when it stalls on you and will not start, does the RPM show on the dash while cranking? That will tell me if the crank sensor is working.
