happy easter----probly the idle air control or throttle body needs cleanin--can use nonchlorinated stuf or use hand and brush -the littl electric motor may be filthy--getta haynes manualor other for details

A long list of things.
Is the check engine light on when you are driving ?
Have you checked the fuel pressure after replacing the pump ?
Have you checked the throttle position sensor ?

Sounds like the pickup modual on distributor gets hot and malfunctions .after it warms up and it fails to start check for spark if no fire to spark plugs replace pickup module.

One possibility is a blocked fuel line or filter. It basically runs out of fuel and you have to wait for it to come through slowly. The other possibility is the ignition system is losing spark as something heats up. You have to wait until it's cooled down before it runs again.

replace the Crank Shaft Position Sensor.

Cold start injector could be bad, or you could have a small vacuum leak, like a cracked hose. A vacuum leak is most noticeable at idle, when engine cold.

you may need a trottle position senor or you are sucking air into the intake from somewhere.

I have a 1988 dodge ram charger with a 318 motor with throttle body. It runs really good when I start it up and drive it for about a half of an hour.
But after that when I step on the throttle a little bit, it hesitates. If I let off a little bit, it will go or if I really step on it, it will go also, but if I just hold it there, it really hesitates If I stop, the idle jumps up and down so much it causes itself to stall. It seems to only do this at low RPM's. If the RPM's are higher it's fine

You more than probably have a gas leak somewhere in the fuel system. If you can smell gasoline, it is leaking somewhere. The lines run along the frame to the engine. The leak might be hard to see or hidden (on top of the fuel tank).

The leak is robbing fuel pressure from the engine, causing it to idle rough, so is probably on the pressure side of the system.

(Most fuel systems, except for "returnless" systems with Pulse width modulated fuel pumps (not very common), have a pressure line and a return line to the tank.
