Have you checked the oil pressure switch. This can turn off the fuel pump if it sees low pressure.

the gauge shows good pressure, and temp. so i hadn't thought of the switch. is that a good or bad only switch? i was thinking of injectors but hopeing for a simpler salution before that. ill check the switch first tho. thank you

Ok check the red wire coming from the oil pressure switch this is the one that goes to the fuel pump relay to shut it off. Run the car up to temp and then check that wire for power once it dies. Let me know what you find.
