Answer

Keep contact means to constantly be touching them.

Because of convention, and only convention, (possibly helped by a famous commercial from the 80s - reach out and touch someone) keep in touch means to talk on a regular basis.

Answer

Keep in contact would be the formal English and generally everyday English as well. I have never heard 'keep contact'
