You need to determine why it's dying. Does it lose spark? Does it lose injector pulse? Do you have fuel pressure? When it dies can you hear the fuel pump running? Buy yourself a TBI fuel pressure gauge and TEE into the system and check your pressure. I believe 9-13 PSI off the top of my head is acceptable.
