My '99 3.0 had the common timing cover gasket leak at 113k. Replaced it, and while i was at it replaced the chain and gears, water pump, fan clutch, thermostat, crank shaft position sensor and radiator. Changed the oil, replaced the coolant. Made sure to make sure that the key holes were lined up on the chain/gears. It started right up, and idled fine for 10 minutes. I drove it around the the block, it felt great, better then ever. I decided to take it down the road and it completely died about 2 miles from my house. Truck was running previously. Any ideas? Battery, alternator and belt are less then a year old.
