My car stalls out at about 30min and its not over heating. Now if I start it and turn it off and start it again I wont get about more than 5min down the road. If I let it cool about 5 to 10min I can get a little further. So starting it more than once equals a stall in less than 5min and if I start it once I get about 30min so Im guessing its coil related. Can any one shed a little light on this.
Thanks in advance.

Most likely an ignition module, symptoms include, will start when cold and when engine gets hot it will fail and then restart when it cools down.

Most can be tested at autoparts stores for free, I would start there, let us know if module checks out.

If you have a timing light with inductive pickup, start engine and put pickup on one wire at a time, pull trigger on light and look at pulsing pattern, if you notice any difference in flashing pattern when changing to different wires, then coil pak is culprit.
