1990 Honda Accord LX, 4Dr, AT, 250,066 miles. Under normal drive and slow to prepare to stop at traffic around 10~15 mph. Car suddenly stall. The first time it happened was two days ago while slow for bump at shopping center. However, car can be start immediately and drive as normal. Today, I drove on highway ramp to merge into highway (down slope) and prepared to stop for red light. Car suddenly stall again. I pulled my car over to the side. I tried to start the car. The first 2-3 times it started and stalled immediately. The 4th time, it started and I can drive it as usual to work. Both stalls happened around 9AM after ~25 minutes drive if this matters. Anyone has any idea of what would go wrong? Thanks in advance!

I’m not a mechanic, but my first suggestion would be a fuel filter or possibly even the pump.
That’s what I would check first if that happened to me.
The 1st thing comes to my mind is ignition switch. I had this part changed 5 years 10 months ago using after market part. It had 59K miles on it. The previous ignition switch was from original and used it for ~19 years with 191K miles on it. The symptom of original switch failure was that I can start engine right away, but stall immediately if I let key go. If I start engine and hold key in II position (starter keeps engage), engine won’t stall. This after market ignition switch acts a little differences. Although it stalled for the first few times, other times works like normal. Is it about to go bad with contacts inside switch? Want to get opinions from other experts who have this type of experiences.
Yesterday on the way home. It stalled again on the street. I cranked and it started and stalled immediately. I started and hold key at crank position, engine keeps running. This is similar problem like I had with ignition switch failure before. Then, I used right hand to hold key in crank position to drive home. This morning I took off ignition switch and take it apart. There isn’t anything obviously bad, but I know it must be contacts problem. I soldered all flat contacts and put everything back. Car can be started right up and running like normal. I will drive it for a few days and post back if it still stalls.
I drove this morning and didn’t see any problem. I think the problem is fixed and it is ignition switch contacts. Hope this will help others.
It’s not the fuel pump. Honda fuel pumps rarely have issues.
By the sound of it you’ve found the problem to be the ignition switch. It’s not the mechanical portion but the electrical portion fastened to the back of the tumbler assembly that’s the issue. It’s not difficult to replace and they aren’t that expensive. It can be purchased separately.
Good luck and keep us posted.
