Hello, you have a connection problem. It sounds like either your positive cable is going bad or your ground cable is going bad. Most of the time it's due to the positive cable. If you have a multi meter you can perform a voltage drop test across the positive wire to see where the issue is.
Well if you have a multi meter you can test from the positive side of the battery. Use the other lead on the meter and put it on a fuse in the fuse panel. It should read 0v. If you are getting voltage your problem is the power wire. You can go from the battery positive to the power on the starter. this should also read 0volts. If voltage is present then the positive cable will need to be replaced.
