In search of a water leak, I removed the muffler(water box) I filled with water and checked for leaks, there wer none ,I turned upside down to get the water out. Then I put the drain plugs in tilted the sportster as high as I could get it. Filled with water not passed the electric box! Also battery was out. No leaks there either. So put it all back together and started motor then I Turned on water hose ran ok then it just died!!! Try to start and it just clicked! Tried another battery and same thing. Baffled !!! I took out spark plugs and put my camera down, no water!!! Put plugs back. Then I took off carbon ring cover and turn drive shaft by hand and it turned . Then motor started ran ok then turned on hose and it ran for about 10 sec the. Died again. Turned off water , turned drive shaft again , started engine ran good turned on hose but this time I revved motor a little more than the last 2. Ran for about 15 min on hose and was fine. Restarted several times and now ok. Any thoughts anyone?
