My timing belt and water pump for Honda Accord 1990 was replaced and used the car for 2- 3 weeks. After driving about 15 minutes, entering the freeway, my car slowed down but the engine still running. Whenever I tried to put it on drive, it died. After 15 minutes It will crank and engine run and then died. When it was brought home, I tried to drive it to the shop which is about 1/4 of a mile from home. It cranked and the engine run and was able to move it about 3 houses and died and the engine never run anymore. I asked the shop about its probable problem and he said it's the distributor. When I was shopping for distributor in the dealership, the mechanic said it might be ignition or the timing belt might have slipped. What could be the possible problem?
