At any time after driving awhile, when I am going under 10 mph, the engine will just shut off. in trying to restart, the engine cranks over just fine but wont start. After 10 to 15 minutes if starts and runs great. Temperature reads fine at stalling. 136k miles.

    Also, heat prone crankshaft sensors give some trouble, cool down a bit, 10-15 min., then be ok, scan test should show this, may have to let your mechanic keep it until it can be checked while acting up. Scanner will confirm no ckp sens. output, or reveal another problem!
