Welcome to the forum.

Check the battery ground connection both at the battery and chassis. Also make sure the connections at the battery are clean and tite.

 

Might be worth having the battery checked also

 

I'm going to guess it's a connection problem from what you are describing. check the battery out, make sure all your grounds are good (even the ground strap from the motor to the frame/firewall wherever it may go) and check back.
