Unhappy 94DI dies when warm, restarts later? fuel??

my 94 DI fires up and runs fine. At about 170 degrees it dies very suddenly, barely chugs at all. it won't restart, just cranks over. if i let it set 5min it'll start up and die again. if i let it set @30 min it'll fire up and stay going for about 10-15min then do it all again. i've narrowed down that its not getting fuel. i replaced the pump on top of the motor and the filter last year and haven't had any problems untill now. there is almost a foot of snow on the ground and my plow truck only runs for 10 mins at a time. no check engine light. please help the newbee... i work on all my own stuff but have limited knowledge of diesel engines. truck has @155k miles on it but its not abused. thanks in advance, eric

change the pump again or you are getting air in the fuel.

injection pump probably going bad , need to check base fuel pressure , should be between 5 and 8 lbs at shrader valve on filter housing area , if so , id bet on injection pump

got 50psi at schrader valve. no pressure drop when it dies. i am hearing a weird air suck or whizzing noise from motor at part throttle. i dont have a buddy to hold throttle so i can narrow it down. truck wouldnt run long enough for me to brick the pedal. if its getting an air bubble it'd have to be at a line or connection right? maybe its just a belt noise or turbo leak? this makes me want to take diesel mechanic classes.....

ive told you wrong info, if this a powerstroke , then fuel pressure is correct , make sure oil is full and in good condition, try to get codes pulled , helps out alot to steer you in the right direction
