JD....check the fuel hose at the bottom of the gas tank mine was kinked and take a look inside gas tank as the filter at the end of the fuel line it may have moved up or is clogged. Mine would idle fine then miss like hell on the road due to fuel starvation also check your battery cables mine was rotted at the post and would heat up then fail and would work after it cooled. Change the condenser....warm her up then take her on the road advance the dist. a bit at a time bring a wrench with you. I hope tclederman will chime in as he has a cure for all things truck related...T/C Steve
