Hot Starts 900 1991

Our problem is with a 1991 940 Turbo. The car will start, but after running a 15 or 20 minutes it refuses to restart. We've replaced the spark plugs, spark plug wires, distributor cap, and rotor. We've also added a bottle of fuel injector cleaner. On a "hot" restart, will run briefly if the gas petal is held down during starting, but will stall immediately. It will restart after an hour and a half. Any comments? (It's a great, solid car and runs well when it does.)

One of three failures:
-fuel injection relay solder cracks
-radio suppression relay solder cracks
-rpm sensor failure

See the fAQ for repair tips.

It could also be the pick-up amplifier, or ingnition module, or whatever that little black thing is called mounted by the headlights.
