Welcome to the forum. When the problem occurs, check voltage circuits at starter relay. Terminal 30 is hot all the time, terminal 86 goes hot with the key in the crank position. Can't rule out security system, the computer grounds coil side of relay.
You need to make sure the battery has a full charge and the connections are good.
