^ I'm playing with a wheel and pedals, I have found this problem on SP too so I'm not sure what's going on. Only mods I have are the '625hp engine for all trucks' mod (but this glitch happens with all trucks) and sweetfx (irrelevant). I only found this problem in the recent update of ATS and the (glitch?) is quite easy to reproduce; simply let your truck roll a little bit down a hill and press the throttle, if the engine stalls, restart the engine. Can anyone try to see if they have the same problem and PM me? Here is a video of how to reproduce the glitch:
