More likely it is just a dirty throttle body. After a while carbon will deposit around the throttle body butterfly valve and not allow it to close completely, a cold start usually requires very little air and more is sneaking past than the engine computer thinks there is. All this is dependent on the fact that you have good spark plugs, wires, and distributor cap and rotor ( if applicable ), and fuel lilter. When anything out of the norm happens like this it is generally a good indication that a tune up is due or past due. The key not turned all the way thing sounds suspicious, but the cheaper option is always the best first plan. If the tune up does not cure the problem then the ignition switch might need to be looked at.

Your 2001 Pontiac grand am has to have key on for 10 min to start?
Your car is equipped with an anti-theft detterent system. Your system is not communicating properly. This could be one of two problems, the first is the ignition switch. In this mechanism there is a micro chip, that is causing the car to disable the fuel pump. The second problem could be a faulty BCM or a combination of both. I had this same problem and had to get a new ignition switch. At first, it works with the 10min on procedure. Eventually it will stop working and your car will not start at all.
