Not sure if this is CIS-E equiped car but if it is, then you may find that 
the 5th (6th) injector may not be working correctly. The next time this
happens, remove the 2-pin connector for the 5th injector and see
if it is getting a signal (12v). If it is not then you are certain this is
causing the
problem. You may find that the temp sensor is not working properly and as
a result the 5th injector not getting a signal. CIS-E injected cars are not
easy to start
when cold, if the 5th inj. is not working.
