Double check battery cables. Make sure they are clean and tight. Also the negative connections on the frame and motor. Also check the connections on the alternator. Also main power cable to fuse panel.

I've checked battery terminals I checked the frame ground and the connections on the altamator still does it I've looked for wires grounding out but nothing truck litterly almost does but then gets power again

Is there suppose to be a ground from the motor to the frame there is not I found one from the frame to the body but that's it
