Okay.. this morning, car started fine!! I drove it to meet my friends and when I tried to start my car again after shutting it off for 5 min, car didnt start.. I tried to jump the car but it didn't start... engine didn't turn over or anything...

after standing outside in 100degree weather for like 10 min, I tried to start my car without jump cable... guess what? car started fine without any problem!

When I got home, I shut the car off and tried to start it again.. It doesn't starts again !!! but after 15-20 minutes or so, car starts fine like nothing is worng with it.

I'm guessing my starter is going out.. what do you guys think??
CAr has new engine, no overheating problems what so ever...

When I checked my alternator and battery from autozone, it was fine..

 

problem fixed... it was dirty 12V input on fusebox..thanks to roadracing7
