Stalling

Stalling
1990 GXE auto 110,000mi
Cleaned all sensor connections.
Did the tap,tap test for the MAF meter. Nothing
Checked the cap and rotor. Good
Tested fuel pressure. Normal
Check for codes. None
All normal.
Car stalled after taking a right turn, 25mph, down a slight hill, very light on the gas.
This was after a 20 minute drive with one stop light.
When it stalled, I put it in neutral, it started right up.
Ran fine for the next 5 minutes of driving.
Let it sit for 45 minutes, started right up.
Drove for 10 minutes with no problem.
I'm thinking the MAF or TPS.
But now maybe a relay.
With the MAF and TPS, if they fail, engine would stall and a code would be set. No codes.
If a relay opened, stalling the engine, would any code be set?????
Any thoughts on which relays to change????
My O2 is old. Probably original. I should really change it.
I know it will run, although poorly, with the O2 disconnected.
But would a bad O2 stall the engine????
Seems to be an on-going problem with 3rd gens.
