I have a 1994 Force 120 that was taken down to the block and completely rebuilt. Carb's were rebuilt and lower unit serviced. This was 11/03. I am on my third tank of gas and while riding at 4500 rpms after 2 hours of riding, the motor shut off instantly. The engine will turn over but it will not fire. I have checked to see if it's getting gas and it looks like it is. I was told that it could be an electrical problem due to the way it shut off immediately versus sputtering to a stop. I have visually checked all the fuses I could find and the wiring looks good. I took the black wire with the yellow stripe off of the block and tried to crank. Still nothing. Do you guys have any suggestions? Thanks!
