Engine Stalls..
 

Hello everyone,
Got a little problem that is driving me crazy, I have a SBC 350 with a TH350 automatic transmission, it was driving and running great until recently. It starts right up and idles fine and it will go into gear and drive perfectly until it warms up (20-30 minutes) then it shuts right off, like if key was turned off. It will start right back up, but as soon as you put it in to gear it will shut off..if I hold the accelerator down I can shift, but as soon as I let go it shuts off.. no hesitation or spattering, just turns off. I Replaced the modulator, and checked all the vacuums it it's all good..if I leave it off for a while it will work fine until it warms up..any suggestions I will greatly appreciate.. JR

Check the coil. If it is weak it will loose most of the spark when it gets hot. Shorted windings.

That would be the first place I would look.

Thanks fellas, I'm going to get one tonight and let you all know..

Got a new Accel Super Coil and things are back to normal.. thanks again for the help!! JR
