Default 93 CHEVY 3500 EXT CAB DUALLY 6.5 TURBO glow plug problems

I bought this truck about 2 weeks ago ran great. started missing so I checked the glow plugs and had a bad one fixed that problem and the miss was gone for a couple days. Nut since I got the truck the glow plugs cycle good when it sits all night but if u stop at the gas station and turn it off it don't want to start and the glow plug lite never comes on unless jumpered were do I start and could this be my miss . miss only happens above 2000 tons any help would be great

start with changing the fuel filter then check the lift pump it could be bad the glow plugs are a known PITA the controller could be bad or the relay bad .
