Start with the basics, and work your way up, Last tune up was? Wires plugs ALL filters? If all that is ok, check for a stuck EGR, then test fuel pump pressure, If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!

and this one!
If the check engine light is on, read the codes, the computer is trying to point you in the right direction.
Readers can be purchased by following the link in my signature file, this is a must do step for all computer controlled cars. I suspect if it has no spark the ignition module is weak/dead, take it out, bring it to Autozone, they can test it for you before you buy a new one.
