Inspect the clutch coil wire...it does pass by some hot parts and can rub on nearby brackets, but your description of working and then poof, it's more likely your clutch coil is dying. If it starts to short out internally, then it will draw more current than it is supposed to thus blowing your fuse. Let's say there are normally 200 windings of wire in coil and let's say each winding is 0.01 ohm (this is just an example). So your coil would normally have a resistance of 2 ohms (200 x 0.01), which at 12V would consume 12/2 or 6 amps (V=IR). Now let's say that the insulation (varnish) between winding 50 and winding 150 breaks down (could be made worse by heat) and now you have a direct short across 100 of your 200 windings...now your resistance drops to 1 ohms and your current increases to 12 amps (12/1)...
