Going about 25mph. Suddenly had to hit the brakes hard! Almost ran a light, Whew! Engine stalled. Started engine , seemed OK. A little later going own street behind a slow truck, about 20mph. Engine dies, pulled over to curb, waited a bit-started engine. Seems OK.

Weekend all fine. Today, went somewhere , got there, pulled up to park, engine died on its own. Started it, drove about another hour on city streets . Engine seems fine.

Symptoms-engine when it stalls then after start the idle is slow rpms. Later, idle rpms comes up. If idle is up, engine wont stall, but I can’t tell if engine is going to stall or go back to a slow idle. .
Opinions please. Thank you.
