Instead of throwing parts at it I would use a fuel pressure gauge and see what the fuel pressure is doing.

10 PSI isn't going to cut it.
Here's the spec
Key On Engine Off 35 - 45 psi Key On Engine Running 30 - 40 psi

Do you have a security light on or flashing when this happens?

no security light but when you turn the key on you get injector pulse and then it loses it. we have now replaced the computer and it is still losing injector pulse
