I have a1989 pontiac gta 305 with a 5 speed. All stock. Up until yesterday I could start the car right up. There would be a little bit of a rough idle. I can drive it ok down the road with no noticable power loss. When I go to turn it off after a 20 -30 minute drive, it will not restart. The engine turns over with no ignition. After the car cools down, it will start right up again. Any help?? I have replaced spark plugs, wires, dis. cap, coil, o2 sensor. UPDATE---Now the car has gotten worse. After the car cools down, I can start it and go about 1/2 mile and then there is a severe loss of power. So much power loss that you cant drive it. Parked it last night and went and got it this am. Drove it home about 4 miles and parked it. Started it up this afternoon and only went 1/2 mile until the power loss. I coasted it almost home and it sits 1/2 way up my driveway! It almost sounds like there is 2 different things going on but mabye the first thing got worse? PS --I dont drive this car everyday, about 100 miles in the last 4 years. Any help would be appreciated.
