Recently my car has been acting really wierd.... First off a couple months ago whenever i tried to start it for the first time of the day it would die immediatly, and do this several times until i would just put the gas to the floor, then it would start... well that stopped, but then my starter started to act funny, when ever the engine is cold the starter works fine, if i start it and drive it for about 10+ mins and shut it off, it won,t turn over, the solenoid clicks and everything but the starter motor doesn't spin unless i click it about 50 times..... it only does this when the engine is warmed up, is my starter bad or do have something else that is bad??

thanks
Chase
