Stalling when stopping and going

Hi there,
Recently whenever my clutch is in and in gear to come to a stop , the rpms drop and the truck stalls out. And also when I am about to go and clutch in and in gear it seems to stall out , but if I let go fast enough then it does jump but does not stall out . If I am at the light and put it in neutral then rpms return back to normal. Is there some sort of sensor causing this.

thank yiu

I adjusted the clutch recently, and while I had my
Brake chambers changed the mechanic looked at clutch some play but nothing terrible , and he readjusted . He said it looked like some metal shaving in it. There is a noise though when it started happening . Like a clink clank sound coming from under the pedal.

 

Thanks guys, turns out it was connections from battery to ECM eventually it didn’t turn on anymore
