Default AP1 starting and idling problem

hi, all. I just got my Ap1, it's very nice taken care from previous owner. It's a 2001 and only has 35k miles when i bought it.

Recently, the car died on my way home after getting gas from BP. I tried to restart immediately, it cranked but did not start. I tried a few times, but no luck. But after 2 to 3 mins, i was able to restart. Started fine and idle fine. I drove home, but again, it died before i got to my driveway.

Occasion 2: I started the engine from cold and let it idle, idle seems fine, but after 2 mins, it choked and died.
Occasion 3: I started the engine from cold, and start driving, within 1 mile, it died.

I have a video of it running and died, i will post a link when i can. But right now, i am collecting some ideas on what to do as my next step. Some of the items are: Main relay, fuel filter, fuel pump, etc. because everything when i start it from cold, it did not hesitate to start, so i don't think it's coil or plug, or battery.

So let me know what you think, any comment is appreciated.

Thanks

Maybe try draining the fuel and refill with good known fuel, you may have bad gas. No pun intended.

Good luck.

No CEL? Could be a clogged IACV.

Update: I was able to start the engine while it was cold in the past few tries. However, i couldn't start just now. It cranked fine, but not able to start. i was trying to see if there is any vacuum leak. But now, vacuum leak seems not very likely.

Is there any easy way to drain the fuel?

thanks

No flashing CEL or pending codes? Do you have a code reader?
Bad gas is like the universal catch-all, and I've never actually seen it happen as much as people suggest it as a fix.
