My '97 Chevy Suburban diesel dies at random times. Nothing seems to trigger it; it usually happens when I'm just driving along, minding my own business; not accelerating or decelerating, turning, stopping, etc. Has happened with the fuel tank at every level: full, half full and quarter tank. When it dies, the dashboard lights do NOT come on. When I turn the key "off" and back "on", the lights come on and the engine will crank fine, but won't start. Ten minutes later, it starts and everything is fine. It may not do it again for weeks, or it may do it again in 10 minutes. This last time, the fuel tank was fairly low -- below a quarter tank -- and it seems to "buck" or "hesitate a little just before it died the first time. The dealer replaced the crankshaft position sensor and the fuel injector pump. When it started doing it again, they ran every diagnostic test they had and could find nothing wrong. Ran fine for a few weeks, then quit three times in 30 minutes. It's back there now.
Besides being misogynist, anybody have any ideas? (I'm literally a little old lady in tennis shoes, the mechanics area all male. She quits on me all the time, but won't do it for the mechanics.)
