Hey guys/gals, Looking for some help. Our 440 is having starting issues. Had the battery tested(ok) rebuilt starter and alternator, changed cable ends,replaced grid solenoid. It will start ten times, shut off for a few minutes wont start put it on the charger hit the key and it starts. Use all day no problems (starts on/off many times) next morning nothing. Repeat charger starts right up. Then it might start 2-3 times 4th nothing. The machine might go days with no problems then it starts doing it again. Any ideas???
