i drove my max in the morning and left it alone for a few hours i start it back up and the motor stumbles like its was not sparking right but when it idles for a few seconds it goes back to normal could this be the tps???

 

more likely dirty IACV, TB or maybe an ignitor or coil pack.

 

Or anyone of the various sensors like Temp sensor, cas, o2, etc etc etc.....................
