hello, can you give me some more information as to how hot the engine gets and how long you have to wait before it will start again?

Customer: replied 1 year ago.
Temp normal , up to couple oh hours before it'll start again
Expert:  Lou P. master tech replied 1 year ago.

Ok. Most common failure is the crank position sensor. It fails when it gets hot and will not restart until it cools down again. Have you replaced this yet ?

Expert:  Lou P. master tech replied 1 year ago.

No I think you misunderstand what I mean by hot.

Expert:  Lou P. master tech replied 1 year ago.

I do not mean overheat

Expert:  Lou P. master tech replied 1 year ago.

I simply mean when the engine gets up to temperature which is between 80-100 C. Then the sensor fails until it cools down.
