my 95 suburban 2500 with the 6.5td has intermittent stalling. A few weeks ago stalled at a red light at idle and wouldn't start. towed to garage. After searching this forum I suspected ignition switch/harness. wiggled wiring harness and started up and drove home no issues. Replaced ignition switch harness and truck started and idled for about 10 mins and died. Upon wiggling wiring harness near where the ignition harness plug is truck started back up. When it stalls there is no dash lights,cranking or anything. radio lights etc still work. PMD is remote mounted in front bumper. Ignition harness connections are tight. I've wiggled and jiggled all wires under the dash and can't replicate the problem to save my life. I'd rather not buy another PMD if its not neccessary. ANY ideas ????
