The car is a 95. The temp gauge stays at 195-200 when driving. It does fine for about an hour of running errands. After an hour, when returning to the car from a 10 minute visit in the store, it refuses to start. The temp has risen a little past the 200 mark. Sometimes it fires, then idles with no power, then dies. Sometimes it coughs. Sometimes nothing. Wait about 45 to 90 minutes, the temp gauge shows about 175, It starts right up. It does this when the weather is hot, 90 +.
Any ideas on what is causing this. A/C does not work.

Heat Soak?

Sort of heat soak is my semi educated guess.
Do you have any engine light codes?
My WAG is that the ignition system is not up to specs from age and does not function adequately to start the car in non ideal condition.
What would I do? Change the fuel filter if u haven't in awhile. Its good to do. Then if there are no codes start testing fuel pressure, plug wires and coil packs (I guess a 95 has the same as a 98) and replace the plugs and anything which is out of spec. Will that fix it? Unfortunately I dunno but its what I would go after unless someone on here knows of a particular crank sensor or something to send ya testing.

Thanks for the reply. There are no codes . I will start with the fuel pump.

Fuel Pressure Regulator.
Longshot; Engine Coolant Temperature (ECT) sensor...

Can he test that with a fuel pressure gauge on start up?

Can he test that with a fuel pressure gauge on start up? Sure; Get the engine up to normal operating temp. Or better, drive it until you're pretty sure the issue will occur. With the engine off, disconnect the vac line from the FPR. If there's any fuel coming from the vac line or the regulator, the regulator is bad. Hook up the fuel gauge and turn key to ON. Compare reading to known good pressure reading. Low reading may indicate weak pump or clogged filter. Start engine and observe gauge as you disconnect the vac line on the FPR, pressure should rise ~5psi or so. If no, again bad regulator...
