Hello. I'm new here. I have a LY6 stock with a LS3 intake truck throttle body, TSP Stage 3 LS3 cam, TH400 reverse valve body, FTI 3600 stall and new Aeromotive pump with DW regulator dead head style in a 2001 Crown Victoria with the Terminator X Max. New LS3 injectors with pressure set at 60 psi. It will start no problem cold, but can only hit 140°F before it dead stalls. No chugging nothing, just cuts off. Voltage is good, idle AFR is 14.5. I'm lost and just need a little help please. Just trying to get it to operating temperature for self learn. Can anyone help on why it's off at +140°F, then hard to restart unless I hold throttle open.
