Trouble starting 93 lincoln

I just recently replaced the EGR VALVE AND SOLENOID, THROTTLE POSITION SENSOR, ELECTRONIC IGNITION, PLUGS, and FUEL FILTER on my 93 lincoln town car. The car will start when it is cold and today it ran for about 10 minutes. When I shut it off and tried to start it again, it turns over but doesn't start. When I leave it and come back the next day it will start right up. :banghead: Help!! Thanks

What about fuel delivery? Check Engine Light? , stored error codes?

I'm thinking the fuel pump should be stress tested, many of us have new ones.
You should monitor the fuel pressure while it's running well, and as it's stalling out.
