11 Tundra AT Oil Temp light and stall at 20mph

For the love of Pete, somebody help! Ha! Let me lay the groundwork of what's going on- Early morning- start truck up and take kids to school. No problems. 1.5 hrs later start truck up to go to work. Immediately stalls. I'll start it up again and it doesn't stall, just idles at like 200-300rpm. I have to get to work so I put it in drive and leave the house. Over the 10mi drive it stalls 4 times while slowing to stop or turn anywhere under 20mph. Every time it stalls the AT Oil Temp light, check engine light and battery lights turn on. Once I restart it the lights are gone. Wth..... ideas??

 

Did you ever find a solution to this problem. Having this exact thing happen to me now ?

 

I’d suggest looking at the fuel pump. Or, if your vehicle is a flex fuel model, checking the % Alcohol reading. Has your fuel economy been abnormally abysmal, with extended cranking to get started?

 

Any OBD2 codes? Maybe try to clean the throttle body and MAF sensor. Is the air filter clean?

 

Wow... apparently I haven't been getting notifications for this thread... lol. Ok- so- problem turned out to be the purge valve on top of the motor. I had replaced it once- didn't fix it the problem. Turned out to be a bad valve from the get go... new FUNCTIONING valve fixed it.
