Check the ignition coil. If the coil is tired it will break down, causing rough running and loss of rpm and fuel economy. It's possible that, without consistent spark maintaining sufficient rpm's, the charging system will also struggle which in turn affects other systems. Coils have an average lifespan of about 10 years before they fail to operate properly.

I am wondering what you mean by a K&N intake? If you mean a K&N filter, they don't always breathe as well as the OE filter and it is important not to lose the cold boxing of the original setup. I am wondering if the performance exhaust included a higher flow CAT and an extractor manifold.

If those two mods are the only changes you have made and assuming the K&N is breathing better and is properly coldboxed, etc. then clearly it is likely the engine with the original valve timing is unhappy without some air resistance at the intake/exhaust back pressure - such things often play an important role in the overall tune/performance of the engine.

My initial instinct is to suggest you take it to a specialist and have the engine management remapped.

check globes and also check fuse - the location maybe in the engine bay in the relay box - sometimes fuse is located there instead of in car fuse box in passenger compartment.

Sorry I can't comment specifically but just wanted to mention most power wheelchairs use lead acid batteries, which is simple and old technology but they can behave strangely when approaching old age or when they begin to fail.
In addition electronic circuits can behave oddly when the supply of power is insufficient.

Testing each battery individually for state of charge and the ability to deliver sufficient current must be the first step in discovering what is wrong.

It is also worth mentioning a lead acid battery must be kept in a high state of charge as if stored discharged they are likely to be permanently damaged after just a few weeks.

If putting 12v on the + contact, you get a spark, check the power feed. If on the - contact, replace the ignition unit.
