Owned the car for about a year with no problems no codes but few weeks ago started stalling once in the morning at the same location about a 1 mile or so from home, sometimes happens when sitting at light others when moving put it in neutral and restart after that no problem. Also having issues filling tank stops a few times learned that can be a vapor canister or vapor canister purge valve not sure if these are related both started around the same time.
I did put Sea Foam in gas and that helped no stalling till new tank of gas with none added.
I went online and saw it could be a number of things:
Plugs and coils
Fuel pump (I bought a fuel filter but this model does not have one it is a strainer connected to fuel pump)
Battery (terminals are clean just tried tightening a bit more today)
PCM recalibrated or flashed
Seems like this is a problem many others have had with no codes not sure where to start, hopefully someone out there can help, thanks

Have you analyzed live data? Checking for codes is just the bare beginning of the diagnostic process.
Plugs and coils
I don't think so. Bad plugs and coils causes misses and rough running, not stalling
Fuel pump (I bought a fuel filter but this model does not have one it is a strainer connected to fuel pump)
very possible. Measure your fuel pressure to find out
Battery (terminals are clean just tried tightening a bit more today)
the battery starts the car. It doesn't power it. The alternator does. Have them both load tested

absolutely. A plugged EVAP system might be causing fuel starvation.
search scotty's video about how to remedy this.
I just hooked up a OBD2 code reader and found a PO455 code showing up saying EVAP system large leak detected any advice on finding I dont have smoke machine if that is my option I will take somewhere to test.

Given that you're dealing with a vehicle nearly 2 decades old it's very likely you have deteriorated hoses or other components. Gas cap is an obvious possibility. If that's not it and physical examination does't reveal the fault you really need a smoke test. If you search youtube you'll find some home-brew solutions to doing a smoke test that may help.
The car is stalling within a few minutes of starting with a "Large Leak" evap code.
The only thing that would cause a drivability issue due to an evap leak would be a leaking purge valve.
Pull it off and see if you can blow through it. You shouldn't be able to
Thanks all for the advice everyone, I do not have a check engine light on so this code in the reader should that be accompanied by a check engine light or could that be an old code? I will check the purge valve seems I saw that somewhere else also saw vapor canister fail and debris in the lines

That could be an old code. For example your gas cap was left loose, a CEL came on but was ignored and the engine was allowed to completed several drive cycles (EVAP checks). Then the CEL could turn off but the code would remain.
