Truck backfired then died wont start.
 

So I'm trying to figure out how to get my truck back up and running. First off the truck would act like it would try to die every once in a while and kick back up. The other day I was driving it backfired axted like it was going to die then it kicked back up but every time I pushed on the gas a little too much it would try to die. Then I was turning right it back fired then it died and now it womt start. It trys to but won't. What could be the problem? I read on another forum something similar to mine. He put I'm a ignition module and it started right up. Should I do that? Any suggestions and advice will help. I'm Young and don't have too much knowledge.
