Hello everyone,

I've been chasing an issue on my 93 RRC for over a year. It starts when cold and will run for about 15 minutes and then just stops running. I'm at my wits end.

I've replaced:
Distributor
Cap\Rotor
Amp Pack relocation
Coil
Plugs
Wires
Temperature Sensor
Idle Bypass Valve
Fuel Pump (before I got it 3 years ago)


Symptoms:
Starts fine when cold and runs at 6-700 RPMs.
Runs for about 15 minutes and during that time idle will hesitate and then catch itself.
Eventually the idle starts to slow, hits ~400 RPM and then shuts off
If I let it sit for a half hour it will start again.

From the research I've done I think I've replaced the usually suspects.

Any help would be greatly appreciated.
Thanks
