engine cuts out when starting and while driving at any and every speed!

This is to expound on my earlier thread regarding my engine cut off problem. Just to recap, I have a 1992 Subaru SVX-LSL. The engine cuts off while I am driving. The cut offs happen at low speeds, at high speeds and sometimes when I start the car, particularly if I've already driven the car and the engine is still warm. In the latter instance, the check engine light will come on and stay on until it dies as I try to drive away. as soon as it starts up without the check engine light coming on, I will then be able to drive away without the engine cutting off. However, it may die again at anytime and at any speed without warning. I've taken it to the dealer three times and the local repair shop twice and neither can find anything wrong except for a bad solenoid on the transmission, which they said can be fixed for about $2,000, however, they won't guarantee that that will fix the problem. As a matter of fact, the local repair shop doesn't think that the solenoid replacement is the problem and recommends not to fix the solenoid until the engine cutting off problem is fixed. I sought advice from you guys before with no real response, but I am trying this again. I also notice that when I first start the car the power light blinks several times before it goes out. Does this mean anything?
