Default 2004 Engine controls acting up, Limp mode

I know I don't have all the information regarding questions that will be asked but I decided to sell my 2004 VP and wouldn't you know it, it began to act up. Every once in a while (seems to happen during braking) it will go into limp mode when approaching a stop sign. Traction control and check engine lights illuminate and a performance inhibited message comes on in the message center. If I pull over and shut the car off for a minute then restart, everything is fine. It takes about another month of driving for this to occur again. I will pull codes when I have an opportunity but does this sound familiar to anyone? Vehicle is at 220,000 miles.


Thanks,
Katitud

I pulled codes this afternoon.
P0121 TPS
P1582 Flight recorder data...Do not know how to extract this info yet
P0300 random misfire
P0301-P0308 misfire all
P0782 Gear Load 2-3
P0783 Gear Load 3-4


Some of these codes may have set due to the battery being dead and an extended start time after charging battery. Codes are cleared, I will drive it and collect more data and codes.

You need an OE-type tool for P1582 and in this case I'd not bother unless further trouble and with a good battery.

Yes, could be tps. When I check it, all voltages are good and wave form checks out. When the failure occurs, there are other modules that set voltage related codes.

With a fully working battery has it flagged the code again? If not, do not mess with TPS.
