Start problems

I went out one morning to start my 2010 Chevy
equinox, it would start all lights came on. I went
into the house to tell my husband, he came out
and was able to start my SUV right up with no
problem. A couple days later I was out driving
around running errands, went to start the car once
leaving the store and it wouldn’t start. Someone
gave me a jump. Drove around again for a couple
of days, got ready to take my kids to school one
morning, it wouldn’t start again, waited a couple of
minutes and tried it again then it started. I took the
children to school came home turn off car and
tried starting it, but nothing. Please help what can
this be.
