I have just bought a k6 and today I have noticed that the fuse labeled 'Fuel' keeps blowing. Its starts fine then after 2 minutes or so it stalls and then will not start until I replace the fuse again. Any ideas? Thanks in advance.

Do you have the proper amp rated fuse in it? It's 15 amp I think.

Yes, its a 15 amp fuse. The battery on my bike is dead so i have been jumping it from a car battery to get it running then i disconnect the car battery and 2 minutes later the fuse goes pop and the engine stops?

Jumping from a car is NOT a good idea.... easy to blow something. Cars have a lot more powerful batteries and charging systems than bikes.
Is your battery totally dead? Or almost completely dead?
Running with a bad or almost totally flat battery is really hard on your bike's charging system. Esp if the volts are low - like if a cell in the battery has gone bad, you might be down a few volts. That can screw up a lot of stuff....

Try fully charging the bike with a battery tender first. Even when i've accidentaly pinched the fuel line lowering the tank i've never had it pop a fuse.:cheers

First of all you have to have a properly working battery before going any further.
I'm fairly sure that the Fuel fuse is 10A. You can see this in the service manual wiring diagrams, FI system wiring diagram, and the Electrical listing in General Information (the listing does get the Headlamp Low fuse listing wrong).
The Fuel fuse supplies power to the ECM, the gauge cluster and, through the fuel pump relay, the fuel pump motor and the injectors. I believe that the ECM and cluster connections are very low power.
It sounds like the fuse will blow after a couple minutes if you turn the ignition on but don't start the bike. If so why not unplug the injectors and see if it still blows? If it does blow, the problem is probably with the fuel pump.

use a DVOM to measure the amperage draw of the fuel pump.

Bill I do know that the 2 headlight fuses are 10amp. I wanna say the fuel pump is 15 because I believe it's the one directly above the light fuse that I had to use a jumper wire.

I'm pretty sure it's 10A. Ignoring the spares, the Fuel fuse is on the lower left of the fuse box. The label on the fuse box door says 10A too. Even the parts book says that there are 5 10A and one 15A fuses. The Fuel fuse sits below the 15A Fan fuse.
The headlamp fuses are contradictory and I'm not exactly sure what's going on. The OEM fuses on my K6 are 10A high and low which agrees with the fuse box label and the Electrical listing. The service manual's wiring diagram says the Headlamp Low fuse is 15A (I now believe it's simply wrong).
OEM fuses are marked PACIFIC (ironically marked with a Littelfuse patent number). They might be available through Suzuki parts but I believe them to be otherwise unavailable in the US. Auto parts store fuses will normally be Littelfuse.
There's some variation but Pacific says that a minifuse that blows at 2 minutes has about a 40% overload, i.e. 14/21 amps for a 10/15 amp fuse.
Might this bike have some electrical additions like a Power Commander?
