Car dies after driving 6 or 7 miles then won't start for @ 1 to 2 hours later.

YOU ARE RIGHT, BAD GAS WON'T FIT EITHER PROBLEM. YOUR PROBLEM MOST LIKELY IS A COMPUTER CAUSED PROBLEM RELATED TO THE TEMPERATURE OF THE ENGINE. YOU NEED TO HAVE THE ENGINE COOLANT TEMP SENDER, INTAKE AIR TEMP SENDER CHECKED FIRST. IF THEY ARE ACCURATE, THEN THE OTHER SENDERS THAT CONTROL FUEL DELIVERY & IGNITION (SPARK) FUNCTIONS NEED INSPECTION. SOMETHING IS EITHER SHUTTING DOWN THE IGNITION SYSTEM OR METERING THE WRONG AMOUNT OF GAS. WHEN THE CAR COOLS DOWN, THE PROBLEM GOES AWAY UNTIL THE ENGINE TEMP RISES. TO ANSWER THE OTHER PART OF THE QUESTION, THE CRANKSHAFT SENSOR TELLS THE PCM WHERE THE CRANKSHAFT IS SO THE PCM CAN TRIGGER SPARKS AT THE SPARK PLUGS AT THE CORRECT TIME, AND ALSO DETERMINES HOW MUCH FUEL TO DELIVER TO THE CYLINDERS AND WHEN TO MAKE THE DELIVERY. EITHER FAILURE CAN CAUSE THE PROBLEM. PERHAPS, A COMPETENT MECHANIC WITH HIS TRUSTY SCAN TOOL NEEDS TO EVALUATE YOUR CARE.
