There is no fuse specifically dedicated to the fuel pump on this year and model of Suburban. This Suburban is equipped with dual tanks and as such has two relay switches, primary and secondary, both of which are located at the main fuse box in the engine bay, that power up the respective fuel pumps.

The closest fuse (15A) controlling either of these relays also powers up the main control module (located beside and below the main fuse box). So, if one needs to disconnect the fuel pumps from functioning, then the only effective method is to disconnect the fuel pump relays.

most likely a fuel pump that has taken a dump. isuzu uses typical crappy gm/ac delco/dephi parts. you would need to drop the fuel tank to replace the fuel pump.
