Try changing coolant temp sensor... located beside of thermostat housing.
This little sensor has all sorts of symptoms.. cost about 10 bucks.
Get it out of the equation. See if it helps.

Check fuel pressure 9 to 14 psi. Could be map sensor. Check coil maybe getting hot.
But sure has symptoms of cts.
