My 2004 Tundra quit last June after I'd started it and wouldn't start again. I tried starting it several times but could only get it to sputter but not quite catch. I've been driving my diesel until yesterday. I went out and tried starting the Tundra after not trying for probably 3 months. It started right up and ran for about 15 minutes before just quitting again. I can turn it over and it kind of tries to catch but can't quite do it. I'd like to know what parts to start replacing or how best to troubleshoot this.Any help would be greatly appreciated.

 

I tried loosening the gas cap in case it might be a venting problem. I put a code reader on it and showed a P1035 code.
The P1035 code is open circuit on O2 sensor. I used my multimeter and found the bad one. I left the bad one disconnected and the truck started right up after I reconnected the battery. It ran for about 10 minutes before shutting off. It wouldn't restart. I disconnected the battery and I replaced the bad sensor (upstream on passenger side). The truck started up again after reconnecting the battery and again ran for 10 minutes. The error code is no longer present. The truck will only restart after it's cooled down but dies after 5 or 10 minutes. No codes so I don't know what to do next. Has anyone experienced this? Any ideas?
