Grunff is absolutely right.Change the electrical and filter tune-up parts first. If after his suggestion you still have the problem, I would do a fuel system check, to rule out the warm-up regulator. It controls how much fuel the engine gets during the warm-up cycle by adjusting the control pressure in the fuel distributor.The check also test and eliminates all the other fuel components,(i.e pump,accumulator,filter,etc...) If that's all good, check for a plugged Catalytic converter (plug a vacuum guage into the system, with a long hose and take a 'friend' along to monitor when it quits), plugged charcoal cannister (in the left fender well), or faulty distributer cutout module ( it has a cutout sensor built in to protect against over-revving).....( I think the morning 'miss' is just coincidental. Does the car completely stall or just lose power momentarily? , The other thing to check is the boost over-pressure sensor, (on a bracket, behind the lower facia, just below the driver's left knee)...it is supposed to momentarily 'kill' the electricity to the fuel pump in an overboost situation, but I've encountered a few bad ones which stayed open lon enough to completely kill the car prior to resetting.
