need to check and see what yer loseing when it dies fuel or spark so put a fuel pressure gauge on it and a in line spark tester and let her run and watch yer fuel pressure
if it stays good have a helper crank the car and see if it has spark if not you changed the coil so now you need a module if fule pressure fall below about 45 you need a pump (if you need a pump have fun)
man those suck
