12 valve when gets hot stalls out
 

Hi I have a 94 12 valve that when it gets up to operating temperature the truck stalls out while driving and idling when this happened it seams like the throttle gets stuck and I here a ticking from what seams to be the injection pump but can't verify have to be driving to here this noise need help any input would be appreciated also it's a 5 speed.
Also when it stalls if I wait 30 seconds and try to start truck it starts right up if I try and start it after it stalls it takes forever to fire
