My 97 tls with 4000 untuched miles stopped running while going to get gas the other day. I did put new NGK's in it about 100 miles ago. After it shut down , It fired up again but as soon as I let the clutch out and put a load on the motor it just stalled. It did this about 3 times and then it would not fire at all. I'm sure it's electrical. Can someone give me a list of components to check ?? I start this bike regularly and keep the battery charged. Please help. MANY THANKS !
