I initially started the tractor it ran for 20 min then I shut it off and when I came back and turned the key and nothing. No instrument panel lights or anything. I checked battery connections all excellent I jumped out starter it cranked fine. I put battery jumpers on still no change. I left it for awhile came back turned on key and my fm radio came on which is very odd because it usually does not unless tractor is running. at that time it started and I used it for what work I was doing. Next day hit the key instrument lights flashed and then dead again. Not sure what to look at now maybe ignition switch?
