Issues Staying running

I have a 88 fiero se with the 2.5L iron duke motor, i paid 200 for the car and it runs fine but once it warms up it just acts as if the motor just shuts off or loses fuel.i was told it was the ignition module from who i bought it from so i went ahead and put 2 new coil packs and ignition module as well as plug wires. Im 17 and trying to fix this car on my own without having to borrow money so im just curious what else it could be? any help is appreciated. thank you have a nice day.

Thought I told you what to check?

You never answered any of my questions....

Thanks, it was the crank sensor, had a bad connection. i replied to the last one but i think i did it wrong. I appreciate it alot, it runs great!
