Stalls out, will start again after 30 minutes or so then will run 2 blocks to 2 miles but stalls again. Each time it will turn over but acts like out of gas. New plugs, fuel filter, air filter and crankcase sensor, passed smog 2 months ago. Engine light on now but wasn't when problem first started.

The Check Engine light means the Engine Computer detected a problem, set a diagnostic fault code, and turned the light on to tell you. It's important now to not disconnect the battery or let it run dead until that code has been read and recorded. The most likely suspect is a failing camshaft position sensor. If it is failing, you won't have spark when it doesn't start.

Have installed camshaft position sensor. If it was fuel pump would it run at all?

If the fuel pump fails the engine will stall within a few seconds. The injectors need fuel pressure to operate and the fuel pump supplies that pressure.

It is extremely rare for a Chrysler fuel pump to fail once it has started up and is running. They almost always fail by failing to start up when starting the engine, so the car leaves you stranded in the driveway or parking lot. GM fuel pump, by contrast, usually fail while you're driving, leaving you coasting to the side of the highway in the middle of nowhere.

You still didn't tell me what the diagnostic fault code number is or whether or not you have spark when the problem occurs, but the fuel pump and pressure are not monitored, so problems with the pump won't turn on the Check Engine light.

My mistake it was a crankshaft sensor we installed first. Put in camshaft position sensor as you recommended and problem solved. You guys are great, thanks for the help.
