Why would the service engine soon light be flashing

Its telling you there's something wrong Tom!!
Look under the hood and do your drivers checks. Is there water in the rad header tank?
Is there oil in the engine?
Is the fan belt in good condition and tight?
When it runs is fluid dripping underneath?
When was it last serviced?

Have a good check around and get back to us.

Sounds like a fuel pressure problem. If the light was on it still has the code stored in the ecm. A good shop can check the code and fuel pressure.

What does the "service engine soon" indicator light specifically mean?

when the service engine soon light is illuminated in your vehicle, it means that the on board self diagnostic system has detected a fault either in the engine, transmission, or accessory controls. when this light is illuminated, it means that there is a code stored in the vehicle memory which can be extracted with a code reader. any garage should be able to do this for you. good luck!

Service Engine Soon light - 2003 Pontiac Grand Am

The loose gas cap is a quick and easy check to perform, so try that first. The service engine light will remain on until the next "cold" start.
I would also recommend visiting your local Auto Zone and ask them to scan your car for trouble codes. They offer this service free of charge, write the codes down and respond back, I can let you know what they are and mean if you decide to have a technician fix the issue.
Good luck, let me know.

Transmission Component Slipping (TCC Stuck off)

code p 1870 refers to transmission component slipping
That can be from dirty oil or a clutch pack or band slipping or low oil pump pressure in the transmission
you say that it occurs on highway driving after 2 hours and that slipping will add friction heat to the transmission oil bringing on the oil temp light
take it to an accredited transmission professional service center that works on your make of vehicle , have the oil changed which require the pan removal
at the same time that will allow the adjustments to be done
when reassembled and refilled , have a pump pressure test done
