Slow start up and beeps a couple of times

I would overhaul the carby and check for corrosion in the main jet and other circuits
if it is a 2 stroke I would check the crank shaft seals as they may be hard and leaking mixture and running lean ( backfiring)

your battery may not be fully charged yet with the quick jump. let it run for a bit with no lights or accesories, no a\c or heat. everything is run off the computer and it need to be fully charged.

My 2000 accent will stall only when hot and will not start till it cools down.

CHECK ALL OF YOUR COIL PACKS,YOU MIGHT HAVE TO REPLACE THEM.

Because the problem you describe is intermittent, it is almost certainly fuel related, either the fuel itself or the carbs on your bike.

Before taking it to a dealer or mechanic (or trying to fix it yourself), get a can of Seafoam (I know Autozone has it) and add it to the fuel. It seems to do an excellent job of cleaming out whatever bad stuff accumulates in fuel systems over time, especially carburetors.

There's an interesting review of it at: http://www.webbikeworld.com/sea-foam/

the iac valve on the throttle body is maybe sticking and the idle speed is to low.that will affect the power steering pump.the air filter has to be clean otherwise the mixture will lean out because of reduced airflow and stall

Your carb may need cleaning. I had the same problem with my Astra. If not then there is too much air getting into the engine.

Check your spark plugs. If they don't have your injector mix right, you could be fouling plugs...

I had the same problem with stalling when slowing down or coming to a stop . Check engine light coming on also . fixed my problem truck now runs like it did when i drove it off the lot in 03. Go get a couple dollors can of Carb Cleaner. take duct work off of Electronic Throttle Body and spray it completely let sit couple seconds and repeat this time take an old toothbrush and after spraying scub infront and around throttle clapper and rerinse with cleaner let air dry and put duct back together . this worked wonderfully for me hope does for you

i think your exhaust might have a leak which is heating up your oil when this happens the engine suffocates and wants to die.
