I've replaced the fuel strainer, replaced the fuel pump and I still will start and only run for a few minutes. Where is the fuel system relay?

Hi,

Are you sure it is fuel related? A bad crankshaft position sensor can also cause you to lose spark.

First, I attached a pic of the relay that powers the fuel pump. It is referred to as the Engine Control Relay. See pic 1. It shows location.

Next, take a look through these two links and let me know if you feel what you experience could mirror what is discussed in link 2 (symptoms).

The interesting thing about a crankshaft position sensor is that it doesn't always turn the check engine light on. Have you checked for diagnostic trouble codes? Also, when it stalls, does it start right back up for you?

Let me know.

Take care,
Joe
