97 talon does dies at random

I have a 97 talon base model, the problem i'm having is it dies completely at random. When this happens there is no fire from the coil at all. it may start in 2 tries or it may start in a week. there is no rhime nor reason, not when it's hot or cold,.. nothing. the code on the check engine light says the coil is bad. I changed it twice, I also changed the ecu. it made absolutely no difference. the ecu was from a junk yard but the odds of getting another 1 with the exact same problem are pretty slim, can anybody help me?

how are the connectors for the coil. power, ground, signal, etc... you might have a loose connector or a bad ground or wire

a bad ground or wire

that or corroded ground/cables

ok thanks for the help, i'll check those things out later,.i know the battery cables are lose do you think that could have anything to do with it? maybe just power surges or something?

When I first got my gs it would die at random and it turned out to be a bad termanl.
