Mcfee03 - I don't mean to sound like a pest, but I want to make sure you know what is meant by saying to check/replace the ignition switch. Your earlier comment seemed to indicate that you thought that since the car started then the ignition switch must be good. But I want to make sure you realize that the starting of the car is only one small part of what the ignition switch does. Also, by ignition switch we are not talking about the tumbler/cylinder that the key goes into. Instead, the ignition switch we are talking about is a conglomeration of around 10 different relay switches. These relays provide power to lots of different systems (including - ahem - the transmission solenoids). It may even affect the MAF sensor, though I'm not certain. These relays can fail/pit over time and cause all sorts of weird electrical gremlins.

Earlier postings gave links to youtube videos showing how to replace this switch.

If you already are aware of the above, then I apologize and don't mean to sound like a know it all. It's your car, of course - but I'd replace that switch. Not very expensive, and not hard or time consuming.

Good luck.
