coil packs

i have a 00 2.4 with 113k. what are the signs of coils going bad?

you start your car, it runs fine until it warms up, then it dies, once it cools down, it will start and run fine for about another ten minutes, until it warms up again, then it will die again

how about cut-outs or "mis-firing" under heavy load such as getting on the interstate?

ive never heard of coil pacs causing a problem like that, usually they just do what i said
