Doy uo have distributor less ignition? If so then it sits right on top of the back valve cover along with any coil packs? Those are very susceptible to heat and so I'd be looking at them. A code 42 from your computer?

Suggested Repair

If the engine has distributorless ignition, inspect the coil packs on the rear valve cover. They are heat-sensitive and can cause bogging and a no-start until the engine cools. Also check whether the computer has set code 42.

Conversation Summary

The owner of a 1990 Oldsmobile Cutlass Ciera with 195,000 miles reports a hot intake manifold, bogging after about 5 to 6 miles, and a no-start until the car sits about 45 minutes. After cooling it starts roughly, then the same hot-running problem returns. The MAF, TPS, fuel pressure regulator, fuel filter, crank sensor, ECM, and thermostat have already been replaced. An expert suggested checking the heat-sensitive coil packs on the rear valve cover if the vehicle has distributorless ignition, and checking for code 42.
