Just to clarify.
When you leave the car for two to three hours you are finding it hard to start?, does the starter engage on the first turn of the key after sitting two to three hours?. I have two suggestions for you to check depending on the answers to the 1st two questions.
1. Make sure the battery is fully charged let the car sit two to three hours, place a multimeter across the battery and get someone to turn the car over for you, check the amount of volts at the battery when cranking should be above 10volts below 10volts the car will not start!!!! the cause? a worn or inefficent starter motor.
2. If the car is turning over fine It could also be the diesal running away from the engine after sitting 2 to 3 hours, you will have a one way valve on your diesel line or in your hand primer to hold the diesel to the engine, this or a cracked pipe can cause the diesel to run away meaning you are cranking a long time to get it to come back up to the engine this is maybe why the car will start 100% if you start every two to three hours as the diesal is never running away from the engine within that time.
Check both what i have mentioned here.
