Blown injecter fuse (10A)

[chevyed]

I own a 1997 Pontiac Bonneville SE.
The car stopped one morning, and would not restart.
It was towed to a shop where, the next morning they installed a new injecter fuse; and the car started.
However, after my driving it that afternoon, for 45 minutes, it stopped again; because of the same blown fuse.
I took it back to the shop, where the next morning they installed a new fuse; and let it run all day. The fuse did not blow.
Would pulling and checking each injecter be the next logical step?

If a fuse blows, there is a high amperage draw on that circuit that needs to be corrected.
Most likely cause is a wire with chaffed insulation contacting a ground (short to ground) or an internally shorted injector.

The fact that after the fuse blows, a new fuse inserted also blows; and that if the car is allowed to sit (in my case, two times for overnight); a new fuse works; indicates an initial heating up (of something) to the point where there is enough resistance to blow the fuse. There is a 'short' temporarily.
