Mazda 3 won't start if keys left in ignition

Has anybody else had this problem??

If I turn off the car and leave the keys in the ignition turned to where I am listening to the radio, the car will not turn back on after a very short amount of time. Like 20 min.

Weird thing is I can completely take out the key and charge my phone overnight in the car and the car will proceed to turn on without any issue.

Anybody else seen this?
