my Kubota M-490 has been giving me trouble in an electrical issue so i recently put a brand new OEM ignition key switch in it yesterday i was unloading items and it was parked emergency brake on also blocked and just sitting at an idle and it died ??? took a little bit but did start back up i have checked cables and the electrical plug in to the dash but it all looks good for some time i would have to tap on the fuel solenoid because it would stick when cold and also would have to hold key longer in the start mode to keep in running any ideas ??? or sugjestions on what to check or look for or test would be much appreciated
