Happy New Year!
I love this forum, I have solved a lot of my problems just by reading what others have posted for solutions. Unfortunately I haven't found a posted solution for the random stalls, it seems, only a few others have encountered. But here's my deal:

1999 GTP, 107K, Aftermarket "Digital Horsepower PCM", open-cone K&N filter, 180 degree Hypertech PowerStat Thermostat, Auxillary Transmission Cooler Kit, 3.4 Pulley, Viper Alarm & Remote Start w/ window and sunroof control mods, aftermarket deck w/ sub.

Replaced CKPS & Cam Sensor, alternator, battery, battery cables 2 years ago before mods, recently replaced plugs and wires, fuel pump & filter & resistor, spark module, igntition switch, small opened wire behind ignition switch, alternator, belt tensionsers, valve cover gasket. I think thats about it - plz forgive me for some of the aftermarket mods, they were done b4 reading some of the more important posts.

While driving car at no specific speed will randomly stall: rpm straight to zero, battery and oil indicator illuminated, tcs illuminates, check guages on HUD, no codes/SES, stereo stays on if on, no flickering of lights. Car used to restart quickly which turned into stalling immediately after restart which turned into not even turning over until the next morning. Typically seems to be below 32 at night in MT when happens I believe this to be more ironic and the good Lord's humor. Run's great otherwise during the day and in the evening just randomly stalls!?

My current next step is checking the crank sensor again. Since I can't get it to stall for the mechanics and we're running out of ideas any help would much be appreciated. Thanks!

Welcome to AF!!

Based on your description this certainly sounds like the Crank Position Sensor is bad. Make sure you purchase an OEM CPS as others have had problems with the aftermarket ones.
