91 buick lesabre starts then dies after a few minutes if not rightaway may or may not start back up at first but will in Neutral or if given a little gas, replaced starter alternator, TPS, harmonic ballancer, fuel filter, short in wiring and somthing else I can't remember. 1 garage says fluids mixing the other said no not that. I have read if you clean the crank position sensor that is all you need but not sure what you say?

    I had the same problem with my 1990 LeSabre. Problem was Cam position sensor. Required pulling the balancer, waterpump, timing set, just to get to a part no bigger than a penny. Dealer quoted me a price of about $500 for repairs. Did all the work myself, including replacing all removed parts with new ones, for about $250. I am so glad I'm mechanically inclined

Voltage regulator

Sounds like a bad connection. The alternator only charges the battery, so if it or the voltage regulator in the alternator fails, the battery would slowly run down, not die all at once.

1995 LeSabre - Starts and runs fine, but engine cuts off without warning. First time, 5mph in a crowded school commute traffic. Put in park, and started right away. Second time, after turning onto...

If the motor gets hot and cuts off and will not start for a period of time the problem would be the crank sensor. The sudden cut off and starting right back up can be due to dirty battery cable connections. Remove them from battery and clean all three of them with a wire brush and replace both bolts.
