Default Flooded cylinders

1997 civic lx. 200k miles. Just had valve ckver gasket, timing belt, cam seals, water pump, efi main relay, ecu, seal kit-injectors, fuel filter, spark plugs all replaced. fuel injectors cleaned, gas tank drained amd refilled.
so with that said here is what its doing now and what I've tried and 2 different shops over the last 3 months have tried....
car will start and run for about 60 seconds just fine. After about 60 seconds the idle goes down to a spudder and struggles to stay running. Step on the gas and it dies. All 4 cylinders flooded. Have to wait at least 6 hours to be able to start it again.
Me and these 2 shops have tested every single sensor and all now test ok. Timing is good. Valves ok. Pistons and rings ok. Can find nothing mechanically wrong. Both shops gave up.
does anyone have any thoughts? It acts like after 60 seconds something is detecting something wrong with the fuel/air and dumps fuel into the cylinders but no error code are generated

Does it start right back up and run another minute?
Maybe the coil or some other primary or secondary ignition issue? Check for wiring damage as well.
If the ignition craps out it might have the same symptom of excess fuel in the combustion chamber.
