1998 Eclipse 68,000 miles 2.0

Ok. I have been trouble shooting this car for 3 months. I have taken it to 3 mechanics and they can't find anything wrong. Here is my problem. Car over heated due to thermostat. I replaced the thermostat and then car would not start. Cranks great but wouldn't start. I replaced the plugs and wires. Finally starts. Ater about 8-10 starts; same thing. Plenty of fire but plugs are fouling (gas not oil). I was told to replace the fuel injector gauge. This is located by the thermostat. Still nothing. No codes or anything. The mechanics have all ran fuel pressure; fuel regulator; checked fuel injectors, timing and OMS (B4 and after start) All check within spec. They have also checked the battery conntections and MAP sensor. Once you get the car started it runs great. No hesitating, missing or anything. Runs like a charm. :) Then won't start. :( Replace plugs; runs like a charm:) Won't start. :( Replace plugs; runs like a charm. :) HELP! I am a single mother and can't afford to continue taking it to anymore mechanics for them to trouble shoot when no one can figure it out. I have picked up a repair book and can not find anything that I haven't already tried. :
