make sure the battery is fully charged,, if the alternator isn't working right , everything is run off the battery for a short time, and it will just die , the lights and other functions like the radio require little voltage to work, so try that first, if it turns over fast ,, then you need to check for fuel, if the pump is weak, it could be not enough pressure to keep the car running

Make sure your battery is fully charged and all terminals and connections are clean, first. If the car still makes a clicking sound near the starter its your starter selonoid. Some vehicle models allow you to just replace the selonoid and others require a whole new starter. Either way you'll probably have to remove the whole starter to accomplish the repair.

i think it's time to replace the battery. have you tried to crank it after someone gave you a jump? if it starts than replace the battery. there's no real way I can tell you how to check the charging system unless the car is running.

If you have heated seats then there is a likelihood that they are not turning off and can be difficult to tell or not when you get in the car and the sun has already been on the seat.

My 02 GTP had this problem and as a matter of fact it got hot enough to start burning me so I pulled the fuse. It is a 15amp fuse located in the glove box compartment, the diagram for it's location is on the inside of the fusebox cover.
