My 1995 toyota camry starts right up but after driving for ten to fifteen min. it shuts off. If i leave it for a while, perhaps a couple of hours it starts right up again.

have your fuel filter replaced

If your putting water in, then there must be water leaving. If you don't see any water on the ground, you might have a blown head gasket. Water is going into engine and out the exhaust. Have some one start and rev the engine up and you see if it is spitting water out exhaust pipe. If you put your hand in front of it, your hands should fell alittle slick from the antifreeze. Don't keep adding plan water because you will eventually run out of antifreeze and cause more damage. You will have to fix soon if it is your head gasket.

Josh, same problem with my suburban, very frustrating. Two issues to check.
Underneath your distributor cap and ECM module there is the pickup coil. The reluctor is most likely corroded really bad. It is about one hour work but you would be surprised how dirty and corroded that area gets. The reluctor is a fixed part of the distributor shaft and the little nubs break magnetic field which is
processed by your onboard computer. If the pulses are not correct the computer is telling your TBI injectors to spray which will flood out your engine. Ten of fifteen minutes later, it will start up again and then die shortly after. Have a new pick up coil on hand too ($10.00) since your in there. My reluctor looked like it was in Vavy Jones locker it was so crusty. Second- the fuel relay. Nororious for developing little cracks on the mini circuit breaker which get wider as voltage and amps increase due to resistance (dirt,moisture). The relay will shut off the fuel pump if the oil pressure signal gets cut, and if your breaker/circuit board is
bad the board heats up and trips off your fuel. When the board cools off in ten or fifteen minutes, starts up and then dies when engine gets warm/hot. It really had me stumped for quite some time. Hope ths cuts your wrench time down considerably.

Take it back to the mechanic who worked on it last and ask for warranty service on it.

Bad ignition coil. Replace.

I HAD SAME PROBLEM, ENDED BEING CRANK SENSOR GETTING WEAK, AFTER HOT THE CRANKING SIGNAL IS TO WEAK TO TRIGGER FIRING.

sounds like ur fuel filter is plugged. with todays newer cars, it's probably located in the gas tank along with the fuel pump...

send me ten dollars and i will be happy to share the solution you SOB.
