Car has 98,000 miles has started to hesitate when starting from a stop. Does not happen all of the time but garage cannot get it to repeat so they cannot fix it. Any thoughts. I have put a great deal of money into this car in the past year seems to be one thing after another.

It sounds like it has jumped time. What year is the car and how many miles. Timing chains can go bad as early as 70,000 miles

If it does this only when warm then it may be the coil pack. To prove it you can warm the car's engine up and when the problem occurs, stop the engine and remove the coil pack. Place it in a bag if cool enough and place in the freezer, ensuring it can't get wet! Once cool, replace the coil pack and start the engine. If it's fine for a minute and then plays up, it's almost certainly the coil pack.

Replace Fuel Pump .

The first issue is the clicking response. That always means the starter isn't getting the voltage it needs which usually means a dead battery. If the battery is good under load testing then it's either the voltage regulator or a bad ground connection. The ground wire may have corroded so check that first and the battery connections. The ground wire bolts to the block. I recommend the you jump start the car after you find the problem. Now go to an auto parts store that will test your ignition system: alternator, battery, etc. while running. O'Reilly does it in MI. The car is old so it may need spark plugs, wires, fuel filter, etc. Candidly, it may be time to take it to a good mechanic.

If the timing belt breaks it could cost you alot more! If it breaks the pistons can slam into a intake or exhaust valve and bend them. This action could also crack the piston. If this happens an engine re-build will be required plus it could leave you stranded somewhere. It is possible you could drive another 30,000 miles without a problem...but do you want to take the chance?

CAR & TRO CLEANER

After checking out alot of Honda/Acura forums I'm finding that many owners experience the same problem you are having. The best explanation I found was at 2carpros:

From what I'm reading, only way to stop the oil loss is a new engine. If your car is running fine, I'd hesitate to change anything with the engine and stock up on oil.

check fuel pump pressure.it should be 41 to 47 psi.

the most common cause of this by far is lights left on by defective switchs, these include the map lights in the visors, the glove box light due to a defective switch, the trunk light and the hood light if equipped, check it at night and look for a faint glow, the other much less common cause is the alternator has a defective diode and allows a small current to pass to ground drawing the battery down..

Hook up a san tool and monitor the system while the problem happens, pay attention to the O2 sensors to see if they go lean, this would indicate a fuel pump pressure problem.
