Default car struggles to start after running...

i been noticing this issue for awhile now. after having driven the car for awhile for a errand 10-20 mins driving...then i come back shortly to start the car, it struggles to start but it will start. i just got new ngk plugs and wires. this was an issue before the new plugs and wires were put in. any ideas what it can be doing this?

thanks

maybe its your altenator, my friends had trouble starting his car and he found the problem was with the altenator.

Sounds like the Altenator is draining the battery. I'd have both checked.

is it struggling to start as in it cranks over slowly for a while then starts OR it cranks over very strong like it were a brand new battery, for a while then starts? if it were your alternator, all your gauge lights would be on, battery light, brake light, oil light etc... if it cranks over slowly, it could be your battery going bad. the battery is only used to start the car, once the car is running the alternator takes over, the battery also serves as a storage unit for the next time you start your car. or it could be your alternator, while the engine is running it doesnt recharge your battery and everything is running off the battery drainning iti so the next time you try and start your car itll crank slowly. have then both checked out. my question is, when you first try to start your car for the day, does it start up fast/fine/no struggle?
