The injectors work for a little whilw and then they stop and then they will start to work in a few days. The ECM is new, the fuel pump and fuel pump relay are new, is there anything else that sends power to the injectors to make them pump?

I had a simiiliar issue with a '93 chevy 350 w/TBI. It would run about 5-25 miles and quit. then restart after about 15 minutes. My mechanic traced back to the injectors not firing, and there is a module located in the distributor [called ?] that supplies the impulse to the injectors that was faulty. That may explain your problem...
