With the symptoms you descibe the most likely components to check are 1) Control Pressure Regulater 2) Thermo time switch 3) Cold start valve 4) some kind of wiring problem It is most likely the control pressure regulater. To verify either check fuel pressures with a gauge set-up or replace with a known good one. When cold the engine is mostly running on the cold start valve. Your troubles seem to disappear at about the time the cold start valve should be shutting off so it is logical that the cold start system is not functioning correctly and the regulater is usually the cause.
