Camry Forums - Toyota Camry Forum - 87 camry runs for 20 min then dies

I have a 87 toyota camry AT 3FSE. One day I noticed a bubbling sound coming from my hood. My coolant in the overflow was boiling. I replaced the thermostat and fixed that problem. I also noticed some oil on my spark plugs. I replaced spark plug tube seals. I was also having starting problems. It would start sometimes and other times I would have power but it wouldnt start. I replaced starter and it fixed that problem. Then I couldnt keep it running for more than 20 min. It would just die and not start and would have a hint of gas smell. I took the distributor off and noticed the coil was cracked and leaking oil. I replaced the coil and the coolant temperature sensor at the same time. Started it up and ran for 20 min. I then replaced the ignition control module. Started it up and it ran for 20 min. then died and wouldnt start. I also cleaned the throttle body as good as I could with out taking it off. I dont know what else to look for. Anybody have any ideas?? I dont know what else could would make it die when reaching operating temp...
