75 chevy c10 cranks, idles good but...
 

Once it warms up and I drive it for a mile or so it stalls (once I come to a stop) and hesitates to crank back up. It has a 350, with new wires, plugs, distributor and the timing is good I believe. Any suggestions on what could be causing this? Sorry if this is a vague question. I'm not a great mechanic.
