When the engine goes into Limp Mode, some major component is not working and it could be the ECU or bad power or ground connections that deteriorates with heat buildup.
Even though no check engine light has shown, I would suggest scanning the ECM to see if any had been recorded.
If scanning does not fiand any codes, try checking the ECM connectors for corrosion, contaminations.
Also check engine and body groundings.
