Today while driving to work, following happened on 3 occassions.

I was going 50-60 miles an hour on the road when a red light or stop sign approaches or I have to take a turn. I slow down by pressing brake pedal and pushing in the clutch which normally would bring the rpm to about 1k and than I will eventually take it out of gear and go to first gear or whatever. But when I am slowing down to turn or slowing down, upon depressing the clutch pedal, the rpms go all the way to 0 and the car just stalls. Everything locks up, steering wheel and all. I can start the car right back up without any problems. It does not have any trouble starting or when its going.

Before if the car has been driven for a bit and I depress the clutch when slowing down, rpms will go to 500rpms and than once I stop or slow down even more, eventually it will go up about 700-800rpms and idle fine, If AC is on it will be 900-1k rpms.

But for some reason, back to back three times when I slowed down by braking and pressing the clutch, it went down to almost 0 and stalled instead of its normal behavior to go to about 500rpms and than bump up to 700-800rpms…..

I checked under the hood for the basics. All lines seem to be fine, nothing is disconnected or leaking from visual inspection. All fluids are full as well.

Anyone else had this problem, any suggestions?

Could it be clutch related? Or vaccum lines not connected somewhere?
I do have a FSM, I will look into that as soon as I get home after work. Anything I should look and check for………thanks for your help…
Thanks
