LOOSING POWER CAR DIES OUT RANDOM
OK so here it goes. 2004 Mustang gt V3 vortex super charger with a dyno (sniper tune). Started experiencing a idle draw.
Had a bad alternator changed it out went to a 150 AMP boch
Changed the spark plugs coils looked good gapped plugs .34 ish
Changed IAC
Check TPS set at 1.00 the .97 then .98 still dies
Pulled MAF was perfectly clean not a spec of dirt.
Took apart all vac hoses put them all back together nice a tight. Found no kinks or vac leaks
I'm reaching out for help on this because I'm stumped please help..

what is your fuel pressure doing when it dies? you should monitor it to make sure it isnt dropping spec is (40psi+boost psi) while driving under acceleration(27-37psi) at idle with a steady reading, and 50-75 psi (key on engine off). does it die at an idle, or while cruising, under boost, etc.? your TPS V was fine to start, it has a range and all of your settings are in it and will not cause an intermittent stall due to closed throttle V.
